Ubuntu 9.10 : krb5 vulnerability (USN-879-1)

medium Nessus Plugin ID 65120

Language:

Synopsis

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

Description

Jeff Blaine, Radoslav Bodo, Jakob Haufe, and Jorgen Wahlsten discovered that the Kerberos Key Distribution Center service did not correctly verify certain network traffic. An unauthenticated remote attacker could send a specially crafted request that would cause the KDC to crash, leading to a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
