Ubuntu 6.06 LTS / 6.10 / 7.04 : libpng vulnerability (USN-472-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

It was discovered that libpng did not correctly handle corrupted CRC
in grayscale PNG images. By tricking a user into opening a specially
crafted PNG, a remote attacker could cause the application using
libpng to crash, resulting in a denial of service.

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, libpng12-dev and / or libpng3
packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
