Update to 0.9.6k:
Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
*) Fix various bugs revealed by running the NISCC test suite:
Stop out of bounds reads in the ASN1 code when presented with
invalid tags (CAN-2003-0543 and CAN-2003-0544).
If verify callback ignores invalid public key errors don't try to check
certificate signature with the NULL public key.
*) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
if the server requested one: as stated in TLS 1.0 and SSL 3.0
*) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
extra data after the compression methods not only for TLS 1.0
but also for SSL 3.0 (as required by the specification).
[Bodo Moeller; problem pointed out by Matthias Loepfe]
*) Change X509_certificate_type() to mark the key as exported/exportable
when it's 512 *bits* long, not 512 bytes.
Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
*) Countermeasure against the Klima-Pokorny-Rosa extension of
Bleichbacher's attack on PKCS #1 v1.5 padding: treat
a protocol version number mismatch like a decryption error
in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
*) Turn on RSA blinding by default in the default implementation
to avoid a timing attack. Applications that don't want it can call
RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
They would be ill-advised to do so in most cases.
[Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
*) Change RSA blinding code so that it works when the PRNG is not
seeded (in this case, the secret RSA exponent is abused as
an unpredictable seed -- if it is not unpredictable, there
is no point in blinding anyway). Make RSA blinding thread-safe
by remembering the creator's thread ID in rsa->blinding and
having all other threads use local one-time blinding factors
(this requires more computation than sharing rsa->blinding, but
avoids excessive locking; and if an RSA object is not shared
between threads, blinding will still be very fast).
Changes between 0.9.6h and 0.9.6i [19 Feb 2003]
*) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
via timing by performing a MAC computation even if incorrrect
block cipher padding has been found. This is a countermeasure
against active attacks where the attacker has to distinguish
between bad padding and a MAC verification error. (CAN-2003-0078)
[Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
Martin Vuagnoux (EPFL, Ilion)]
Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
*) New function OPENSSL_cleanse(), which is used to cleanse a section of
memory from it's contents. This is done with a counter that will
place alternating values in each byte. This can be used to solve
two issues: 1) the removal of calls to memset() by highly optimizing
compilers, and 2) cleansing with other values than 0, since those can
be read through on certain media, for example a swap space on disk.
*) Bugfix: client side session caching did not work with external caching,
because the session->cipher setting was not restored when reloading
from the external cache. This problem was masked, when
SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
(Found by Steve Haslam <email@example.com>.)
*) Fix client_certificate (ssl/s2_clnt.c): The permissible total
length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
[Zeev Lieber <firstname.lastname@example.org>]
*) Undo an undocumented change introduced in 0.9.6e which caused
repeated calls to OpenSSL_add_all_ciphers() and
OpenSSL_add_all_digests() to be ignored, even after calling
*) Change the default configuration reader to deal with last line not
being properly terminated.
*) Change X509_NAME_cmp() so it applies the special rules on handling
DN values that are of type PrintableString, as well as RDNs of type
emailAddress where the value has the type ia5String.
[email@example.com via Richard Levitte]
*) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
the bitwise-OR of the two for use by the majority of applications
wanting this behaviour, and update the docs. The documented
behaviour and actual behaviour were inconsistent and had been
changing anyway, so this is more a bug-fix than a behavioural
[Geoff Thorpe, diagnosed by Nadav Har'El]
*) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
(the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
*) Fix initialization code race conditions in
SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
[Patrick McCormick <firstname.lastname@example.org>, Bodo Moeller]
*) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
the cached sessions are flushed, as the remove_cb() might use ex_data
contents. Bug found by Sam Varshavchik <email@example.com>
(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.
