Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : update-manager vulnerabilities (USN-1284-1)

medium Nessus Plugin ID 56971

Language:

Synopsis

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

Description

David Black discovered that Update Manager incorrectly extracted the downloaded upgrade tarball before verifying its GPG signature. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to replace arbitrary files.
(CVE-2011-3152)

David Black discovered that Update Manager created a temporary directory in an insecure fashion. A local attacker could possibly use this flaw to read the XAUTHORITY file of the user performing the upgrade. (CVE-2011-3154)

This update also adds a hotfix to Update Notifier to handle cases where the upgrade is being performed from CD media.

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 auto-upgrade-tester, update-manager and / or update-notifier packages.
