Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : dpkg vulnerability (USN-2820-1)

High Nessus Plugin ID 87108

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Hanno Boeck discovered that the dpkg-deb tool incorrectly handled certain old style Debian binary packages. If a user or an automated system were tricked into unpacking a specially crafted binary package, a remote attacker could possibly use this issue to execute arbitrary code.

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 dpkg package.
