Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Joel Johnson, Brian Almeida, and Shawn Emery discovered that Kerberos did not correctly verify certain packet structures. An unauthenticated remote attacker could send specially crafted traffic to cause the KDC or kadmind services to crash, leading to a denial of service.
(CVE-2010-1320, CVE-2010-1321).
