Ubuntu 5.10 / 6.06 LTS / 6.10 : libpng vulnerability (USN-383-1)

Ubuntu Security Notice (C) 2006-2016 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 :

Tavis Ormandy discovered that libpng did not correctly calculate the
size of sPLT structures when reading an image. By tricking a user or
an automated system into processing a specially crafted PNG file, an
attacker could exploit this weakness to crash the application using
the library.

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 packages.

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 2.3
