Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
+ *) Change the declaration of needed Kerberos libraries to use EX_LIBS
+ instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
+ removed entirely.
+ [Richard Levitte]
+
+ *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
+ seems that in spite of existing for more than a year, many application
+ author have done nothing to provide the necessary callbacks, which
+ means that this particular engine will not work properly anywhere.
+ This is a very unfortunate situation which forces us, in the name
+ of usability, to give the hw_ncipher.c a static lock, which is part
+ of libcrypto.
+ NOTE: This is for the 0.9.7 series ONLY. This hack will never
+ appear in 0.9.8 or later. We EXPECT application authors to have
+ dealt properly with this when 0.9.8 is released (unless we actually
+ make such changes in the libcrypto locking code that changes will
+ have to be made anyway).
+ [Richard Levitte]
+
+ *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
+ octets have been read, EOF or an error occurs. Without this change
+ some truncated ASN1 structures will not produce an error.
+ [Steve Henson]
+
+ *) Disable Heimdal support, since it hasn't been fully implemented.
+ Still give the possibility to force the use of Heimdal, but with
+ warnings and a request that patches get sent to openssl-dev.
+ [Richard Levitte]
+
+ *) Add the VC-CE target, introduce the WINCE sysname, and add
+ INSTALL.WCE and appropriate conditionals to make it build.
+ [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
+
+ *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and
+ cygssl-x.y.z.dll, where x, y and z are the major, minor and
+ edit numbers of the version.
+ [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
+
+ *) Introduce safe string copy and catenation functions
+ (BUF_strlcpy() and BUF_strlcat()).
+ [Ben Laurie (CHATS) and Richard Levitte]
+
+ *) Avoid using fixed-size buffers for one-line DNs.
+ [Ben Laurie (CHATS)]
+
+ *) Add BUF_MEM_grow_clean() to avoid information leakage when
+ resizing buffers containing secrets, and use where appropriate.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid using fixed size buffers for configuration file location.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid filename truncation for various CA files.
+ [Ben Laurie (CHATS)]
+
+ *) Use sizeof in preference to magic numbers.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid filename truncation in cert requests.
+ [Ben Laurie (CHATS)]
+
+ *) Add assertions to check for (supposedly impossible) buffer
+ overflows.
+ [Ben Laurie (CHATS)]
+
+ *) Don't cache truncated DNS entries in the local cache (this could
+ potentially lead to a spoofing attack).
+ [Ben Laurie (CHATS)]
+
+ *) Fix various buffers to be large enough for hex/decimal
+ representations in a platform independent manner.
+ [Ben Laurie (CHATS)]
+
+ *) Add CRYPTO_realloc_clean() to avoid information leakage when
+ resizing buffers containing secrets, and use where appropriate.
+ [Ben Laurie (CHATS)]
+
+ *) Add BIO_indent() to avoid much slightly worrying code to do
+ indents.
+ [Ben Laurie (CHATS)]
+
+ *) Convert sprintf()/BIO_puts() to BIO_printf().
+ [Ben Laurie (CHATS)]
+
+ *) buffer_gets() could terminate with the buffer only half
+ full. Fixed.
+ [Ben Laurie (CHATS)]
+
+ *) Add assertions to prevent user-supplied crypto functions from
+ overflowing internal buffers by having large block sizes, etc.
+ [Ben Laurie (CHATS)]
+
+ *) New OPENSSL_assert() macro (similar to assert(), but enabled
+ unconditionally).
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused copy of key in RC4.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
+ [Ben Laurie (CHATS)]
+
+ *) Fix off-by-one error in EGD path.
+ [Ben Laurie (CHATS)]
+
+ *) If RANDFILE path is too long, ignore instead of truncating.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and incorrectly sized X.509 structure
+ CBCParameter.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and dangerous function knumber().
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and dangerous structure, KSSL_ERR.
+ [Ben Laurie (CHATS)]
+
+ *) Protect against overlong session ID context length in an encoded
+ session object. Since these are local, this does not appear to be
+ exploitable.
+ [Ben Laurie (CHATS)]
+
+ *) Change from security patch (see 0.9.6e below) that did not affect
+ the 0.9.6 release series:
+
+ 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 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.
*) Clean old EAY MD5 hack from e_os.h.
[Richard Levitte]
- Changes between 0.9.6g and 0.9.6h [xx XXX xxxx]
+ 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.
+ [Geoff Thorpe]
+
+ *) 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 <steve@araqnid.ddts.net>.)
+ [Lutz Jaenicke]
+
+ *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
+ length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
+ [Zeev Lieber <zeev-l@yahoo.com>]
+
+ *) 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
+ EVP_cleanup().
+ [Richard Levitte]
+
+ *) Change the default configuration reader to deal with last line not
+ being properly terminated.
+ [Richard Levitte]
+
+ *) 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.
+ [stefank@valicert.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
+ change.
+ [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).
+ [Bodo Moeller]
+
+ *) 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(),
+ ssl2_get_cipher_by_char(),
+ ssl3_get_cipher_by_char().
+ [Patrick McCormick <patrick@tellme.com>, 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 <mrsam@courier-mta.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.
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
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 master key in Kerberos-enabled versions.
- (CAN-2002-0657)

-
*) Remote buffer overflow in SSL3 protocol - an attacker could
supply an oversized session ID to a client. (CAN-2002-0656)

Changes between 0.9.6c and 0.9.6d [9 May 2002]
*) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
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
