Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-1367-1 fixed vulnerabilities in libpng. This provides the
corresponding update for Thunderbird.

Jueri Aedla discovered that libpng did not properly verify the size
used when allocating memory during chunk decompression. If a user or
automated system using libpng were tricked into opening a specially
crafted image, an attacker could exploit this to cause a denial of
service or execute code with the privileges of the user invoking the
program. (CVE-2011-3026).

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 thunderbird package.
