(CVE-2006-4343) + [Tavis Ormandy and Will Drewry, Google Security Team] + + *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites + match only those. Before that, "AES256-SHA" would be interpreted + as a pattern and match "AES128-SHA" too (since AES128-SHA got + the same strength classification in 0.9.7h) as we currently only + have a single AES bit in the ciphersuite description bitmap. + That change, however, also applied to ciphersuite strings such as + "RC4-MD5" that intentionally matched multiple ciphersuites -- + namely, SSL 2.0 ciphersuites in addition to the more common ones + from SSL 3.0/TLS 1.0. + + So we change the selection algorithm again: Naming an explicit + ciphersuite selects this one ciphersuite, and any other similar + ciphersuite (same bitmap) from *other* protocol versions. + Thus, "RC4-MD5" again will properly select both the SSL 2.0 + ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite. + + Since SSL 2.0 does not have any ciphersuites for which the + 128/256 bit distinction would be relevant, this works for now. + The proper fix will be to use different bits for AES128 and + AES256, which would have avoided the problems from the beginning; + however, bits are scarce, so we can only do this in a new release + (not just a patchlevel) when we can change the SSL_CIPHER + definition to split the single 'unsigned long mask' bitmap into + multiple values to extend the available space. + + [Bodo Moeller] + + Changes between 0.9.8b and 0.9.8c [05 Sep 2006] + + *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher + (CVE-2006-4339) [Ben Laurie and Google Security Team] + + *) 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.
