OpenSSL CHANGES
_______________
- Changes between 0.9.8 and 0.9.8a [XX xxx XXXX]
+ Changes between 0.9.8b and 0.9.8c [xx XXX xxxx]
- *) Avoid small subgroup attacks in Diffie-Hellman.
+ *) Add AES IGE and biIGE modes.
+ [Ben Laurie]
+
+ *) 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 "ECCdraft" ciphersuites more thoroughly. Now special
+ treatment in ssl/ssl_ciph.s makes sure that these ciphersuites
+ cannot be implicitly activated as part of, e.g., the "AES" alias.
+ However, please upgrade to OpenSSL 0.9.9[-dev] for
+ non-experimental use of the ECC ciphersuites to get TLS extension
+ support, which is required for curve and point format negotiation
+ to avoid potential handshake problems.
+ [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]
+
+ *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key
+ versions), which is now available for royalty-free use
+ (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html).
+ Also, add Camellia TLS ciphersuites from RFC 4132.
+
+ To minimize changes between patchlevels in the OpenSSL 0.9.8
+ series, Camellia remains excluded from compilation unless OpenSSL
+ is configured with 'enable-camellia'.
+ [NTT]
+
+ *) Disable the padding bug check when compression is in use. The padding
+ bug check assumes the first packet is of even length, this is not
+ necessarily true if compresssion is enabled and can result in false
+ positives causing handshake failure. The actual bug test is ancient
+ code so it is hoped that implementations will either have fixed it by
+ now or any which still have the bug do not support compression.
+ [Steve Henson]
+
+ Changes between 0.9.8a and 0.9.8b [04 May 2006]
+
+ *) When applying a cipher rule check to see if string match is an explicit
+ cipher suite and only match that one cipher suite if it is.
+ [Steve Henson]
+
+ *) Link in manifests for VC++ if needed.
+ [Austin Ziegler <halostatue@gmail.com>]
+
+ *) Update support for ECC-based TLS ciphersuites according to
+ draft-ietf-tls-ecc-12.txt with proposed changes (but without
+ TLS extensions, which are supported starting with the 0.9.9
+ branch, not in the OpenSSL 0.9.8 branch).
+ [Douglas Stebila]
+
+ *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
+ opaque EVP_CIPHER_CTX handling.
+ [Steve Henson]
+
+ *) Fixes and enhancements to zlib compression code. We now only use
+ "zlib1.dll" and use the default __cdecl calling convention on Win32
+ to conform with the standards mentioned here:
+ http://www.zlib.net/DLL_FAQ.txt
+ Static zlib linking now works on Windows and the new --with-zlib-include
+ --with-zlib-lib options to Configure can be used to supply the location
+ of the headers and library. Gracefully handle case where zlib library
+ can't be loaded.
+ [Steve Henson]
+
+ *) Several fixes and enhancements to the OID generation code. The old code
+ sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
+ handle numbers larger than ULONG_MAX, truncated printing and had a
+ non standard OBJ_obj2txt() behaviour.
+ [Steve Henson]
+
+ *) Add support for building of engines under engine/ as shared libraries
+ under VC++ build system.
+ [Steve Henson]
+
+ *) Corrected the numerous bugs in the Win32 path splitter in DSO.
+ Hopefully, we will not see any false combination of paths any more.
+ [Richard Levitte]
+
+ Changes between 0.9.8 and 0.9.8a [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)]
+
+ *) Add two function to clear and return the verify parameter flags.
+ [Steve Henson]
+
+ *) Keep cipherlists sorted in the source instead of sorting them at
+ runtime, thus removing the need for a lock.
+ [Nils Larsch]
+
+ *) Avoid some small subgroup attacks in Diffie-Hellman.
[Nick Mathewson and Ben Laurie]
*) Add functions for well-known primes.
Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
+ [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after
+ OpenSSL 0.9.8.]
+
*) Add libcrypto.pc and libssl.pc for those who feel they need them.

differing sizes.

- Changes between 0.9.7g and 0.9.7h [XX xxx XXXX]
+ Changes between 0.9.7j and 0.9.7k [xx XXX xxxx]
+
+ *) 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:

+
+ The latter two were purportedly from

+ [Bodo Moeller]

+ 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.
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++
Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
