Hi,

the following CVE (Common Vulnerabilities & Exposures) id was
published for krb5.

CVE-2010-1321[0]:
| 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.
|
| This is an implementation vulnerability in MIT krb5, and not a
| vulnerability in the Kerberos protocol.
|
| An authenticated remote attacker can cause a GSS-API application
| server (including the Kerberos administration daemon kadmind) to crash
| by sending a malformed GSS-API token that induces a null pointer
| dereference.

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.

There is a new upstream release which fixes these issues.
