Ubuntu 6.06 LTS / 8.04 LTS / 8.10 : apt vulnerabilities (USN-762-1)

critical Nessus Plugin ID 37762

Synopsis

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

Description

Alexandre Martani discovered that the APT daily cron script did not check the return code of the date command. If a machine is configured for automatic updates and is in a time zone where DST occurs at midnight, under certain circumstances automatic updates might not be applied and could become permanently disabled. (CVE-2009-1300)

Michael Casadevall discovered that APT did not properly verify repositories signed with a revoked or expired key. If a repository were signed with only an expired or revoked key and the signature was otherwise valid, APT would consider the repository valid.

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.
