Description Tomas Hoger 2010-12-07 13:47:51 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-7270  to
the following vulnerability:

OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180.

> a different vulnerability than CVE-2010-4180.

While CVE description lists these vulnerabilities as different, they are related.  The use of SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG gives an attacker possibility to changed ciphersuite in the stored session (CVE-2010-4180).  The impact of that flaw is greater in pre-0.9.8j versions, as session ciphersuite can be changed to one of those that are not enabled on the server side (CVE-2008-7270).  See bug #659462, comment #0 for the details.
