Ubuntu 14.04 LTS : dpkg vulnerability (USN-2183-2)

high Nessus Plugin ID 73820

Synopsis

The remote Ubuntu host is missing a security update.

Description

USN-2183-1 fixed a vulnerability in dpkg. Javier Serrano Polo discovered that the fix introduced a vulnerability in releases with an older version of the patch utility. This update fixes the problem.

Jakub Wilk discovered that dpkg incorrectly certain paths and symlinks when unpacking source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could modify files outside the target unpack directory, leading to a denial of service or potentially gaining access to the system.

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.
