Synopsis:	Moderate: openssl security update

Issue date:	2010-12-13

CVE Names:	CVE-2010-4180



A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server 

code. A remote attacker could possibly use this flaw to change the 

ciphersuite associated with a cached session stored on the server, if 

the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option, 

possibly forcing the client to use a weaker ciphersuite after resuming 

the session. (CVE-2010-4180)



Note: With this update, setting the 

SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this 

bug workaround can no longer be enabled.



For the update to take effect, all services linked to the OpenSSL 

library must be restarted, or the system rebooted.
