Description Tomas Hoger 2008-05-27 09:29:36 UTC 
CERT/FI identified following issue affecting OpenSSL:

Testing using the Codenomicon TLS test suite discovered a flaw in the
handling of server name extension data in OpenSSL 0.9.8f and OpenSSL
0.9.8g.  If OpenSSL has been compiled using the non-default TLS server
name extensions, a remote attacker could send a carefully crafted
packet to a server application using OpenSSL and cause a crash.
(CVE-2008-0891).

Please note this issue does not affect any other released versions of
OpenSSL, and does not affect versions compiled without TLS server name
extensions.
