Ubuntu 7.04 / 7.10 : libcairo regression (USN-550-2)

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 :

USN-550-1 fixed vulnerabilities in Cairo. The upstream fixes were
incomplete, and under certain situations, applications using Cairo
would crash with a floating point error. This update fixes the
problem.

We apologize for the inconvenience.

Peter Valchev discovered that Cairo did not correctly decode PNG image
data. By tricking a user or automated system into processing a
specially crafted PNG with Cairo, a remote attacker could execute
arbitrary code with user privileges.

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 :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
