OpenSSL CHANGES
_______________
- Changes between 0.9.7g and 0.9.7h [XX xxx XXXX]
+ Changes between 0.9.7l and 0.9.7m [xx XXX xxxx]
+
+ *) Remove redundant features: hash file source, editing of test vectors
+ modify fipsld to use external fips_premain.c signature.
+ [Steve Henson]
+
+ *) New perl script mkfipsscr.pl to create shell scripts or batch files to
+ run algorithm test programs.
+ [Steve Henson]
+
+ *) Make algorithm test programs more tolerant of whitespace.
+ [Steve Henson]
+
+ *) Have SSL/TLS server implementation tolerate "mismatched" record
+ protocol version while receiving ClientHello even if the
+ ClientHello is fragmented. (The server can't insist on the
+ particular protocol version it has chosen before the ServerHello
+ message has informed the client about his choice.)
+ [Bodo Moeller]
+
+ *) Load error codes if they are not already present instead of using a
+ static variable. This allows them to be cleanly unloaded and reloaded.
+ [Steve Henson]
+
+ Changes between 0.9.7k and 0.9.7l [28 Sep 2006]
+
+ *) Introduce limits to prevent malicious keys being able to
+ cause a denial of service. (CVE-2006-2940)
+ [Steve Henson, Bodo Moeller]
+
+ *) Fix ASN.1 parsing of certain invalid structures that can result
+ in a denial of service. (CVE-2006-2937) [Steve Henson]
+
+ *) Fix buffer overflow in SSL_get_shared_ciphers() function.
+ (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team]
+
+ *) Fix SSL client code which could crash if connecting to a
+ malicious SSLv2 server. (CVE-2006-4343)
+ [Tavis Ormandy and Will Drewry, Google Security Team]
+
+ *) Change ciphersuite string processing so that an explicit
+ ciphersuite selects this one ciphersuite (so that "AES256-SHA"
+ will no longer include "AES128-SHA"), and any other similar
+ ciphersuite (same bitmap) from *other* protocol versions (so that
+ "RC4-MD5" will still include both the SSL 2.0 ciphersuite and the
+ SSL 3.0/TLS 1.0 ciphersuite). This is a backport combining
+ changes from 0.9.8b and 0.9.8d.
+ [Bodo Moeller]
+
+ Changes between 0.9.7j and 0.9.7k [05 Sep 2006]
+
+ *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher
+ (CVE-2006-4339) [Ben Laurie and Google Security Team]
+
+ *) Change the Unix randomness entropy gathering to use poll() when
+ possible instead of select(), since the latter has some
+ undesirable limitations.
+ [Darryl Miles via Richard Levitte and Bodo Moeller]
+
+ *) Disable rogue ciphersuites:
+
+ - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+ - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+ - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+ The latter two were purportedly from
+ draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+ appear there.
+
+ Also deactive the remaining ciphersuites from
+ draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
+ unofficial, and the ID has long expired.
+ [Bodo Moeller]
+
+ *) Fix RSA blinding Heisenbug (problems sometimes occured on
+ dual-core machines) and other potential thread-safety issues.
+ [Bodo Moeller]
+
+ Changes between 0.9.7i and 0.9.7j [04 May 2006]
+
+ *) Adapt fipsld and the build system to link against the validated FIPS
+ module in FIPS mode.
+ [Steve Henson]
+
+ *) Fixes for VC++ 2005 build under Windows.
+ [Steve Henson]
+
+ *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make
+ from a Windows bash shell such as MSYS. It is autodetected from the
+ "config" script when run from a VC++ environment. Modify standard VC++
+ build to use fipscanister.o from the GNU make build.
+ [Steve Henson]
+
+ Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
+
+ *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
+ The value now differs depending on if you build for FIPS or not.
+ BEWARE! A program linked with a shared FIPSed libcrypto can't be
+ safely run with a non-FIPSed libcrypto, as it may crash because of
+ the difference induced by this change.
+ [Andy Polyakov]
+
+ Changes between 0.9.7g and 0.9.7h [11 Oct 2005]
+
+ *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+ (part of SSL_OP_ALL). This option used to disable the
+ countermeasure against man-in-the-middle protocol-version
+ rollback in the SSL 2.0 server implementation, which is a bad
+ idea. (CVE-2005-2969)
+
+ [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+ for Information Security, National Institute of Advanced Industrial
+ Science and Technology [AIST], Japan)]
+
+ *) Minimal support for X9.31 signatures and PSS padding modes. This is
+ mainly for FIPS compliance and not fully integrated at this stage.
+ [Steve Henson]
+
+ *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
+ the exponentiation using a fixed-length exponent. (Otherwise,
+ the information leaked through timing could expose the secret key
+ after many signatures; cf. Bleichenbacher's attack on DSA with
+ biased k.)
+ [Bodo Moeller]
*) Make a new fixed-window mod_exp implementation the default for
RSA, DSA, and DH private-key operations so that the sequence of
Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
+ [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
+ OpenSSL 0.9.8.]
+
*) Fixes for newer kerberos headers. NB: the casts are needed because
the 'length' field is signed on one version and unsigned on another
with no (?) obvious way to tell the difference, without these VC++
