Description Jan Lieskovsky 2010-02-17 17:56:49 UTC
A denial of service flaw was found in Kerberos's GSS-API spnego
security mechanism implementation. A remote attacker could use
this flaw to cause gss-server crash via invalid ContextFlags
for the reqFlags field in the NegTokenInit in spnego_mech.c,
which triggers an assertion failure. Similar vulnerability than
CVE-2009-0845.

PGP-signed patch from upstream will be available at:
