Ubuntu 8.04 LTS / 9.10 / 10.04 LTS / 10.10 : avahi vulnerability (USN-1084-1)

Medium Nessus Plugin ID 52580

Synopsis

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

Description

It was discovered that Avahi incorrectly handled empty UDP packets. A remote attacker could send a specially crafted packet and cause Avahi to hang, resulting in 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.
