- Changes between 0.9.8k and 0.9.9 [xx XXX xxxx]
+ Changes between 0.9.8k and 1.0 [xx XXX xxxx]
+
+ *) Add ECDHE and PSK support to DTLS.
+ [Michael Tuexen <tuexen@fh-muenster.de>]
+
+ *) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't
+ be used on C++.
+ [Steve Henson]
+
+ *) Add "missing" function EVP_MD_flags() (without this the only way to
+ retrieve a digest flags is by accessing the structure directly. Update
+ EVP_MD_do_all*() and EVP_CIPHER_do_all*() to include the name a digest
+ or cipher is registered as in the "from" argument. Print out all
+ registered digests in the dgst usage message instead of manually
+ attempting to work them out.
+ [Steve Henson]
+
+ *) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello:
+ this allows the use of compression and extensions. Change default cipher
+ string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2
+ by default unless an application cipher string requests it.
+ [Steve Henson]
+
+ *) Alter match criteria in PKCS12_parse(). It used to try to use local
+ key ids to find matching certificates and keys but some PKCS#12 files
+ don't follow the (somewhat unwritten) rules and this strategy fails.
+ Now just gather all certificates together and the first private key
+ then look for the first certificate that matches the key.
+ [Steve Henson]
+
+ *) Support use of registered digest and cipher names for dgst and cipher
+ commands instead of having to add each one as a special case. So now
+ you can do:
+
+ openssl sha256 foo
+
+ as well as:
+
+ openssl dgst -sha256 foo
+
+ and this works for ENGINE based algorithms too.
+
+ [Steve Henson]
*) Update Gost ENGINE to support parameter files.
[Victor B. Wagner <vitus@cryptocom.ru>]
*) Change 'Configure' script to enable Camellia by default.
[NTT]
+ Changes between 0.9.8k and 0.9.8l [xx XXX xxxx]
+
+ *) Don't check self signed certificate signatures in X509_verify_cert():
+ it just wastes time without adding any security. As a useful side effect
+ self signed root CAs with non-FIPS digests are now usable in FIPS mode.
+ [Steve Henson]
+
+ *) In dtls1_process_out_of_seq_message() the check if the current message
+ is already buffered was missing. For every new message was memory
+ allocated, allowing an attacker to perform an denial of service attack
+ with sending out of seq handshake messages until there is no memory
+ left. Additionally every future messege was buffered, even if the
+ sequence number made no sense and would be part of another handshake.
+ So only messages with sequence numbers less than 10 in advance will be
+ buffered.
+ [Robin Seggelmann, discovered by Daniel Mentz]
+
+ *) Records are buffered if they arrive with a future epoch to be
+ processed after finishing the corresponding handshake. There is
+ currently no limitation to this buffer allowing an attacker to perform
+ a DOS attack with sending records with future epochs until there is no
+ memory left. This patch adds the pqueue_size() function to detemine
+ the size of a buffer and limits the record buffer to 100 entries.
+ [Robin Seggelmann, discovered by Daniel Mentz]
+
+ *) Keep a copy of frag->msg_header.frag_len so it can be used after the
+ parent structure is freed.
+ [Daniel Mentz]
+
+ *) Handle non-blocking I/O properly in SSL_shutdown() call.
+ [Darryl Miles <darryl-mailinglists@netbauds.net>]
+
+ *) Add 2.5.4.* OIDs
+ [Ilya O. <vrghost@gmail.com>]
+
Changes between 0.9.8j and 0.9.8k [25 Mar 2009]
*) Don't set val to NULL when freeing up structures, it is freed up by
