Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : libpng vulnerability (USN-1417-1)

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 :

It was discovered that libpng incorrectly handled certain memory
operations. 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.

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 libpng12-0 package.

Risk factor :

Medium / CVSS Base Score : 6.8
