This makes it possible + to determine whether the BIO is the one explicitly called or as a result + of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so + it handles reference counts correctly and doesn't zero out the I/O bio + when it is not being explicitly popped. WARNING: applications which + included workarounds for the old buggy behaviour will need to be modified + or they could free up already freed BIOs. + [Steve Henson] + + *) Rename uni2asc and asc2uni functions to OPENSSL_uni2asc and + OPENSSL_asc2uni the original names were too generic and cause name + clashes on Netware. + [Guenter ] + + *) Add ECDHE and PSK support to DTLS. + [Michael Tuexen ] + + *) 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.

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 ] + + *) Add 2.5.4.* OIDs + [Ilya O. ] + + 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 + underlying code.

(CVE-2009-0789) + [Paolo Ganci ] + + *) Fix bug where return value of CMS_SignerInfo_verify_content() was not + checked correctly. This would allow some invalid signed attributes to + appear to verify correctly. (CVE-2009-0591) + [Ivan Nestlerode ] + + *) Reject UniversalString and BMPString types with invalid lengths. This + prevents a crash in ASN1_STRING_print_ex() which assumes the strings have + a legal length.
