Description Vincent Danen 2010-04-14 23:40:28 EDT 
A null pointer dereference flaw was found in the MIT krb5 GSS-API library where certain invalid GSS-API tokens could cause a GSS-API acceptor (server, such as kadmind) to crash.  An authenticated remote attacker could take advantage of this flaw to cause GSS-API application servers, that link against the GSS-API library, to crash.

This flaw affects all known releases of MIT krb5 up to and including krb5-1.8.1.

A patch to correct this is available from http://web.mit.edu/kerberos/advisories/2010-005-patch.txt

This issue is known as CVE-2010-1321.

Acknowledgements:

Red Hat would like to thank the MIT Kerberos Team for responsibly reporting this issue.  Upstream acknowledges Shawn Emery of Oracle as the original reporter.
