Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ *) Extend the BIGNUM API by creating new macros that behave like
+ functions
+
+ void BN_set_sign(BIGNUM *a, int neg);
+ int BN_get_sign(const BIGNUM *a);
+
+ and avoid the need to access 'a->neg' directly in applications.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Implement fast modular reduction for pseudo-Mersenne primes
+ used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
+ EC_GROUP_new_curve_GFp() will now automatically use this
+ if applicable.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Add new lock type (CRYPTO_LOCK_BN).
+ [Bodo Moeller]
+
+ *) Change the ENGINE framework to automatically load engines
+ dynamically from specific directories unless they could be
+ found to already be built in or loaded. Move all the
+ current engines except for the cryptodev one to a new
+ directory engines/.
+ The engines in engines/ are built as shared libraries if
+ the "shared" options was given to ./Configure or ./config.
+ Otherwise, they are inserted in libcrypto.a.
+ /usr/local/ssl/engines is the default directory for dynamic
+ engines, but that can be overriden at configure time through
+ the usual use of --prefix and/or --openssldir, and at run
+ time with the environment variable OPENSSL_ENGINES.
+ [Geoff Thorpe and Richard Levitte]
+
+ *) Add Makefile.shared, a helper makefile to build shared
+ libraries. Addapt Makefile.org.
+ [Richard Levitte]
+
+ *) Add version info to Win32 DLLs.
+ [Peter 'Luna' Runestig" <peter@runestig.com>]
+
+ *) Add new 'medium level' PKCS#12 API. Certificates and keys
+ can be added using this API to created arbitrary PKCS#12
+ files while avoiding the low level API.
+
+ New options to PKCS12_create(), key or cert can be NULL and
+ will then be omitted from the output file. The encryption
+ algorithm NIDs can be set to -1 for no encryption, the mac
+ iteration count can be set to 0 to omit the mac.
+
+ Enhance pkcs12 utility by making the -nokeys and -nocerts
+ options work when creating a PKCS#12 file. New option -nomac
+ to omit the mac, NONE can be set for an encryption algorithm.
+ New code is modified to use the enhanced PKCS12_create()
+ instead of the low level API.
+ [Steve Henson]
+
+ *) Extend ASN1 encoder to support indefinite length constructed
+ encoding. This can output sequences tags and octet strings in
+ this form. Modify pk7_asn1.c to support indefinite length
+ encoding. This is experimental and needs additional code to
+ be useful, such as an ASN1 bio and some enhanced streaming
+ PKCS#7 code.
+
+ Extend template encode functionality so that tagging is passed
+ down to the template encoder.
+ [Steve Henson]
+
+ *) Let 'openssl req' fail if an argument to '-newkey' is not
+ recognized instead of using RSA as a default.
+ [Bodo Moeller]
+
+ *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
+ As these are not official, they are not included in "ALL";
+ the "ECCdraft" ciphersuite group alias can be used to select them.
+ [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
+
+ *) Add ECDH engine support.
+ [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
+
+ *) Add ECDH in new directory crypto/ecdh/.
+TODO: more general interface (return x coordinate, not its hash)
+TODO: bug: pad x with leading zeros if necessary
+ [Douglas Stebila (Sun Microsystems Laboratories)]
+
+ *) Let BN_rand_range() abort with an error after 100 iterations
+ without success (which indicates a broken PRNG).
+ [Bodo Moeller]
+
+ *) Change BN_mod_sqrt() so that it verifies that the input value
+ is really the square of the return value. (Previously,
+ BN_mod_sqrt would show GIGO behaviour.)
+ [Bodo Moeller]
+
+ *) Add named elliptic curves over binary fields from X9.62, SECG,
+ and WAP/WTLS; add OIDs that were still missing.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Extend the EC library for elliptic curves over binary fields
+ (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
+ New EC_METHOD:
+
+ EC_GF2m_simple_method
+
+ New API functions:
+
+ EC_GROUP_new_curve_GF2m
+ EC_GROUP_set_curve_GF2m
+ EC_GROUP_get_curve_GF2m
+ EC_POINT_set_affine_coordinates_GF2m
+ EC_POINT_get_affine_coordinates_GF2m
+ EC_POINT_set_compressed_coordinates_GF2m
+
+ Point compression for binary fields is disabled by default for
+ patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
+ enable it).
+
+ As binary polynomials are represented as BIGNUMs, various members
+ of the EC_GROUP and EC_POINT data structures can be shared
+ between the implementations for prime fields and binary fields;
+ the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
+ are essentially identical to their ..._GFp counterparts.
+ (For simplicity, the '..._GFp' prefix has been dropped from
+ various internal method names.)
+
+ An internal 'field_div' method (similar to 'field_mul' and
+ 'field_sqr') has been added; this is used only for binary fields.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
+ through methods ('mul', 'precompute_mult').
+
+ The generic implementations (now internally called 'ec_wNAF_mul'
+ and 'ec_wNAF_precomputed_mult') remain the default if these
+ methods are undefined.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New function EC_GROUP_get_degree, which is defined through
+ EC_METHOD. For curves over prime fields, this returns the bit
+ length of the modulus.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New functions EC_GROUP_dup, EC_POINT_dup.
+ (These simply call ..._new and ..._copy).
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
+ Polynomials are represented as BIGNUMs (where the sign bit is not
+ used) in the following functions [macros]:
+
+ BN_GF2m_add
+ BN_GF2m_sub [= BN_GF2m_add]
+ BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
+ BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
+ BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
+ BN_GF2m_mod_inv
+ BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
+ BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
+ BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
+ BN_GF2m_cmp [= BN_ucmp]
+
+ (Note that only the 'mod' functions are actually for fields GF(2^m).
+ BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
+
+ For some functions, an the irreducible polynomial defining a
+ field can be given as an 'unsigned int[]' with strictly
+ decreasing elements giving the indices of those bits that are set;
+ i.e., p[] represents the polynomial
+ f(t) = t^p[0] + t^p[1] + ... + t^p[k]
+ where
+ p[0] > p[1] > ... > p[k] = 0.
+ This applies to the following functions:
+
+ BN_GF2m_mod_arr
+ BN_GF2m_mod_mul_arr
+ BN_GF2m_mod_sqr_arr
+ BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
+ BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
+ BN_GF2m_mod_exp_arr
+ BN_GF2m_mod_sqrt_arr
+ BN_GF2m_mod_solve_quad_arr
+ BN_GF2m_poly2arr
+ BN_GF2m_arr2poly
+
+ Conversion can be performed by the following functions:
+
+ BN_GF2m_poly2arr
+ BN_GF2m_arr2poly
+
+ bntest.c has additional tests for binary polynomial arithmetic.
+
+ Two implementations for BN_GF2m_mod_div() are available.
+ The default algorithm simply uses BN_GF2m_mod_inv() and
+ BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
+ if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
+ copyright notice in crypto/bn/bn_gf2m.c before enabling it).
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Add new error code 'ERR_R_DISABLED' that can be used when some
+ functionality is disabled at compile-time.
+ [Douglas Stebila <douglas.stebila@sun.com>]
+
+ *) Change default behaviour of 'openssl asn1parse' so that more
+ information is visible when viewing, e.g., a certificate:
+
+ Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
+ mode the content of non-printable OCTET STRINGs is output in a
+ style similar to INTEGERs, but with '[HEX DUMP]' prepended to
+ avoid the appearance of a printable string.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
+ functions
+ EC_GROUP_set_asn1_flag()
+ EC_GROUP_get_asn1_flag()
+ EC_GROUP_set_point_conversion_form()
+ EC_GROUP_get_point_conversion_form()
+ These control ASN1 encoding details:
+ - Curves (i.e., groups) are encoded explicitly unless asn1_flag
+ has been set to OPENSSL_EC_NAMED_CURVE.
+ - Points are encoded in uncompressed form by default; options for
+ asn1_for are as for point2oct, namely
+ POINT_CONVERSION_COMPRESSED
+ POINT_CONVERSION_UNCOMPRESSED
+ POINT_CONVERSION_HYBRID
+
+ Also add 'seed' and 'seed_len' members to EC_GROUP with access
+ functions
+ EC_GROUP_set_seed()
+ EC_GROUP_get0_seed()
+ EC_GROUP_get_seed_len()
+ This is used only for ASN1 purposes (so far).
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Add 'field_type' member to EC_METHOD, which holds the NID
+ of the appropriate field type OID. The new function
+ EC_METHOD_get_field_type() returns this value.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Add functions
+ EC_POINT_point2bn()
+ EC_POINT_bn2point()
+ EC_POINT_point2hex()
+ EC_POINT_hex2point()
+ providing useful interfaces to EC_POINT_point2oct() and
+ EC_POINT_oct2point().
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Change internals of the EC library so that the functions
+ EC_GROUP_set_generator()
+ EC_GROUP_get_generator()
+ EC_GROUP_get_order()
+ EC_GROUP_get_cofactor()
+ are implemented directly in crypto/ec/ec_lib.c and not dispatched
+ to methods, which would lead to unnecessary code duplication when
+ adding different types of curves.
+ [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
+
+ *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
+ arithmetic, and such that modified wNAFs are generated
+ (which avoid length expansion in many cases).
+ [Bodo Moeller]
+
*) Add a function EC_GROUP_check_discriminant() (defined via
EC_METHOD) that verifies that the curve discriminant is non-zero.
*) Add ECDSA in new directory crypto/ecdsa/.
- Add applications 'openssl ecdsaparam' and 'openssl ecdsa'
- (these are variants of 'openssl dsaparam' and 'openssl dsa').
+ Add applications 'openssl ecparam' and 'openssl ecdsa'
+ (these are based on 'openssl dsaparam' and 'openssl dsa').
ECDSA support is also included in various other files across the
library. Most notably,
- X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
them suitable for ECDSA where domain parameters must be
- extracted before the specific public key.
+ extracted before the specific public key;
+ - ECDSA engine support has been added.
[Nils Larsch <nla@trustcenter.de>]
*) Include some named elliptic curves, and add OIDs from X9.62,
- SECG, and WAP/WTLS. The curves can be obtained from the new
- functions
- EC_GROUP_new_by_nid()
- EC_GROUP_new_by_name()
- Also add a 'nid' field to EC_GROUP objects, which can be accessed
- via
+ SECG, and WAP/WTLS. Each curve can be obtained from the new
+ function
+ EC_GROUP_new_by_nid(),
+ and the list of available named curves can be obtained with
+ EC_get_builtin_curves().
+ Also add a 'curve_name' member to EC_GROUP objects, which can be
+ accessed via
EC_GROUP_set_nid()
EC_GROUP_get_nid()
[Nils Larsch <nla@trustcenter.de, Bodo Moeller]
- Changes between 0.9.6d and 0.9.7 [XX xxx 2002]
+ Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
+
+ *) Change from security patch (see 0.9.6e below) that did not affect
+ the 0.9.6 release series:
- OpenSSL 0.9.6a/0.9.6b/0.9.6c/0.9.6d (bugfix releases, 5 Apr 2001,
- 9 July 2001, 21 Dec 2001, XX xxx 2002) and OpenSSL 0.9.7 were developed
- in parallel, based on OpenSSL 0.9.6.
+ Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized master key in Kerberos-enabled versions.
+ (CAN-2002-0657)
+ [Ben Laurie (CHATS)]
- Change log entries are tagged as follows:
- -) applies to 0.9.6a/0.9.6b/0.9.6c/0.9.6d only
- *) applies to 0.9.6a/0.9.6b/0.9.6c/0.9.6d and 0.9.7
- +) applies to 0.9.7 only
+ *) Change the SSL kerb5 codes to match RFC 2712.
+ [Richard Levitte]
+
+ *) Make -nameopt work fully for req and add -reqopt switch.
+ [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
+
+ *) The "block size" for block ciphers in CFB and OFB mode should be 1.
+ [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
+
+ *) Make sure tests can be performed even if the corresponding algorithms
+ have been removed entirely. This was also the last step to make
+ OpenSSL compilable with DJGPP under all reasonable conditions.
+ [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
+
+ *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
+ to allow version independent disabling of normally unselected ciphers,
+ which may be activated as a side-effect of selecting a single cipher.
+
+ (E.g., cipher list string "RSA" enables ciphersuites that are left
+ out of "ALL" because they do not provide symmetric encryption.
+ "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
+ [Lutz Jaenicke, Bodo Moeller]
+
+ *) Add appropriate support for separate platform-dependent build
+ directories. The recommended way to make a platform-dependent
+ build directory is the following (tested on Linux), maybe with
+ some local tweaks:
+
+ # Place yourself outside of the OpenSSL source tree. In
+ # this example, the environment variable OPENSSL_SOURCE
+ # is assumed to contain the absolute OpenSSL source directory.
+ mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
+ cd objtree/"`uname -s`-`uname -r`-`uname -m`"
+ (cd $OPENSSL_SOURCE; find . -type f -o -type l) | while read F; do
+ mkdir -p `dirname $F`
+ ln -s $OPENSSL_SOURCE/$F $F
+ done
+
+ To be absolutely sure not to disturb the source tree, a "make clean"
+ is a good thing. If it isn't successfull, don't worry about it,
+ it probably means the source directory is very clean.
+ [Richard Levitte]
+
+ *) Make sure any ENGINE control commands make local copies of string
+ pointers passed to them whenever necessary. Otherwise it is possible
+ the caller may have overwritten (or deallocated) the original string
+ data when a later ENGINE operation tries to use the stored values.
+ [Götz Babin-Ebell <babinebell@trustcenter.de>]
- +) Make object definitions compliant to LDAP (RFC2256): SN is the short
- form for "surname", serialNumber has no short form (Michael Bell
- <michael.bell@rz.hu-berlin.de>).
- [Lutu Jaenicke]
+ *) Improve diagnostics in file reading and command-line digests.
+ [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
+
+ *) Add AES modes CFB and OFB to the object database. Correct an
+ error in AES-CFB decryption.
+ [Richard Levitte]
+
+ *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
+ allows existing EVP_CIPHER_CTX structures to be reused after
+ calling EVP_*Final(). This behaviour is used by encryption
+ BIOs and some applications. This has the side effect that
+ applications must explicitly clean up cipher contexts with
+ EVP_CIPHER_CTX_cleanup() or they will leak memory.
+ [Steve Henson]
+
+ *) Check the values of dna and dnb in bn_mul_recursive before calling
+ bn_mul_comba (a non zero value means the a or b arrays do not contain
+ n2 elements) and fallback to bn_mul_normal if either is not zero.
+ [Steve Henson]
+
+ *) Fix escaping of non-ASCII characters when using the -subj option
+ of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
+ [Lutz Jaenicke]
+
+ *) Make object definitions compliant to LDAP (RFC2256): SN is the short
+ form for "surname", serialNumber has no short form.
+ Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
+ therefore remove "mail" short name for "internet 7".
+ The OID for unique identifiers in X509 certificates is
+ x500UniqueIdentifier, not uniqueIdentifier.
+ Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
+ [Lutz Jaenicke]
- +) Add an "init" command to the ENGINE config module and auto initialize
+ *) Add an "init" command to the ENGINE config module and auto initialize
ENGINEs. Without any "init" command the ENGINE will be initialized
after all ctrl commands have been executed on it. If init=1 the
ENGINE is initailized at that point (ctrls before that point are run
init=0 then the ENGINE will not be iniatialized at all.
[Steve Henson]
- +) Fix the 'app_verify_callback' interface so that the user-defined
+ *) Fix the 'app_verify_callback' interface so that the user-defined
argument is actually passed to the callback: In the
SSL_CTX_set_cert_verify_callback() prototype, the callback
declaration has been changed from
a dummy argument can be added to their callback functions.

OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
This allows older applications to transparently support certain
OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.

[Steve Henson]
- +) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
+ *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
Adjust NIDs and EVP layer.
[Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
- +) Config modules support in openssl utility.

Most commands now load modules from the config file,
though in a few (such as version) this isn't done

use "openssl_conf" if filename is NULL use default openssl config file.
[Steve Henson]
- +) Add an argument to OPENSSL_config() to allow the use of an alternative
+ *) Add an argument to OPENSSL_config() to allow the use of an alternative
config section name. Add a new flag to tolerate a missing config file
and move code to CONF_modules_load_file().
[Steve Henson]
- +) Support for crypto accelerator cards from Accelerated Encryption

compatibility with existing code. In particular the 'ctx' parameter does
not have to be to be initialized before the call to EVP_DigestInit() and
it is tidied up after a call to EVP_DigestFinal(). New function

By default, clients may request session resumption even during
renegotiation (if session ID contexts permit); with this option,
session resumption is possible only in the first handshake.

functions. This change also alters the storage and management of global
ex_data state - it's now all inside ex_data.c and all "class" code (eg.
RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
has a return value to indicate success or failure.
[Geoff Thorpe]

reference counts. This performs normal REF_PRINT/REF_CHECK macros on
the operation, and provides a more encapsulated way for external code

correcting its structure. This means that calls to DES functions
now have to pass a pointer to a des_key_schedule instead of a
plain des_key_schedule (which was actually always a pointer
(Note that a later change renames 'des_...' into 'DES_...'.)
[Ben Laurie]

+ (see [openssl.org #212]).
+ [Geoff Thorpe, Lutz Jaenicke]
+
+ *) Fix typo in OBJ_txt2obj which incorrectly passed the content
+ length, instead of the encoding length to d2i_ASN1_OBJECT.
+ [Steve Henson]
+
+ Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
+
+ *) [In 0.9.6g-engine release:]
+ Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
+ [Lynn Gazis <lgazis@rainbow.com>]
+
+ Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
+
+ *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
+ and get fix the header length calculation.
+ [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
+ Alon Kantor <alonk@checkpoint.com> (and others),
+ Steve Henson]
+
+ *) Use proper error handling instead of 'assertions' in buffer
+ overflow checks added in 0.9.6e. This prevents DoS (the
+ assertions could call abort()).
+ [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
+
+ Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
+
+ *) Add various sanity checks to asn1_get_length() to reject
+ the ASN1 length bytes if they exceed sizeof(long), will appear
+ negative or the content length exceeds the length of the
+ supplied buffer.
+ [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
+
+ *) Fix cipher selection routines: ciphers without encryption had no flags
+ for the cipher strength set and where therefore not handled correctly
+ by the selection routines (PR #130).
+ [Lutz Jaenicke]
+
+ *) Fix EVP_dsa_sha macro.
+ [Nils Larsch]
+
+ *) New option
+ SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
+ for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
+ that was added in OpenSSL 0.9.6d.
+
+ As the countermeasure turned out to be incompatible with some
+ broken SSL implementations, the new option is part of SSL_OP_ALL.
+ SSL_OP_ALL is usually employed when compatibility with weird SSL
+ implementations is desired (e.g. '-bugs' option to 's_client' and
+ 's_server'), so the new option is automatically set in many
+ applications.
+ [Bodo Moeller]
+
+ *) Changes in security patch:
+
+ Changes marked "(CHATS)" were sponsored by the Defense Advanced
+ Research Projects Agency (DARPA) and Air Force Research Laboratory,
+ Air Force Materiel Command, USAF, under agreement number
+ F30602-01-2-0537.
+
+ *) Add various sanity checks to asn1_get_length() to reject
+ the ASN1 length bytes if they exceed sizeof(long), will appear
+ negative or the content length exceeds the length of the
+ supplied buffer. (CAN-2002-0659)
+ [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
+
+ *) Assertions for various potential buffer overflows, not known to
+ happen in practice.
+ [Ben Laurie (CHATS)]
+
+ *) Various temporary buffers to hold ASCII versions of integers were
+ too small for 64 bit platforms. (CAN-2002-0655)
+ [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
+
+ *) Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized session ID to a client. (CAN-2002-0656)
+ [Ben Laurie (CHATS)]
+
+ *) Remote buffer overflow in SSL2 protocol - an attacker could
+ supply an oversized client master key. (CAN-2002-0656)
+ [Ben Laurie (CHATS)]
+
+ Changes between 0.9.6c and 0.9.6d [9 May 2002]
+
+ *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
+ encoded as NULL) with id-dsa-with-sha1.
+ [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
+
+ *) Check various X509_...() return values in apps/req.c.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
+ an end-of-file condition would erronously be flagged, when the CRLF
+ was just at the end of a processed block. The bug was discovered when
+ processing data through a buffering memory BIO handing the data to a
+ BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
+ <ptsekov@syntrex.com> and Nedelcho Stanev.
+ [Lutz Jaenicke]
+
+ *) Implement a countermeasure against a vulnerability recently found
+ in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
+ before application data chunks to avoid the use of known IVs
+ with data potentially chosen by the attacker.
+ [Bodo Moeller]
+
+ *) Fix length checks in ssl3_get_client_hello().
+ [Bodo Moeller]
+
+ *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
+ to prevent ssl3_read_internal() from incorrectly assuming that
+ ssl3_read_bytes() found application data while handshake
+ processing was enabled when in fact s->s3->in_read_app_data was
+ merely automatically cleared during the initial handshake.
+ [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
*) Fix object definitions for Private and Enterprise: they were not
recognized in their shortname (=lowercase) representation. Extend
value is 0.
[Richard Levitte]
- *) Add the configuration target linux-s390x.
- [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
-
*) [In 0.9.6d-engine release:]
Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
[Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
+ *) Add the configuration target linux-s390x.
+ [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
+
*) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
variable as an indication that a ClientHello message has been
