Ubuntu 14.04 LTS : dpkg vulnerability (USN-2566-1)

critical Nessus Plugin ID 82697

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2566-1 advisory.

 Jann Horn discovered that dpkg incorrectly validated signatures when extracting local source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could bypass signature verification checks.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
