Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : libpng vulnerabilities (USN-913-1)

Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 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 properly initialize memory when
decoding certain 1-bit interlaced images. If a user or automated
system were tricked into processing crafted PNG images, an attacker
could possibly use this flaw to read sensitive information stored in
memory. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 8.10 and
9.04. (CVE-2009-2042)

It was discovered that libpng did not properly handle certain
excessively compressed PNG images. If a user or automated system were
tricked into processing a crafted PNG image, an attacker could
possibly use this flaw to consume all available resources, resulting
in a denial of service. (CVE-2010-0205).

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 :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:C)
