Description Tomas Hoger 2008-05-27 09:36:21 UTC 
CERT/FI identified following issue affecting OpenSSL:

Testing using the Codenomicon TLS test suite discovered a flaw if the
'Server Key exchange message' is omitted from a TLS handshake in
OpenSSL 0.9.8f and OpenSSL 0.9.8g.  If a client connects to a
malicious server with particular cipher suites, the server could cause
the client to crash.  (CVE-2008-1672).

Please note this issue does not affect any other released versions of
OpenSSL.
