Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : libpng vulnerability (USN-1402-1)

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 did not properly process compressed
chunks. 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
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
