Mandriva Linux Security Advisory MDVSA-2011:184
http://www.mandriva.com/security/
_______________________________________________________________________

Package : krb5
Date : December 12, 2011
Affected: 2011.
_______________________________________________________________________

Problem Description:

A vulnerability has been discovered and corrected in krb5:

The process_tgs_req function in do_tgs_req.c in the Key Distribution
Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.2 allows
remote authenticated users to cause a denial of service (NULL pointer
dereference and daemon crash) via a crafted TGS request that triggers
an error other than the KRB5_KDB_NOENTRY error (CVE-2011-1530).

The updated packages have been patched to correct this issue.
