Detail

A vulnerability has been found and corrected in krb5:

Certain invalid GSS-API tokens can cause a GSS-API acceptor (server) to crash due to a null pointer dereference in the GSS-API library (CVE-2010-1321).

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

The updated packages have been patched to correct this issue.
