Ubuntu 14.04 LTS : APT vulnerability (USN-2353-1)

critical Nessus Plugin ID 77816

Synopsis

The remote Ubuntu host is missing a security update.

Description

It was discovered that APT incorrectly handled certain http URLs. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to cause APT to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2014-6273)

In addition, this update fixes regressions introduced by the USN-2348-1 security update: APT incorrectly handled file:/// sources on a different partition, incorrectly handled Dir::state::lists set to a relative path, and incorrectly handled cdrom: sources.

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.
