Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : libcairo regression (USN-550-3)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 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. A bug in font glyph
rendering was uncovered as a result of the new memory allocation
routines. In certain situations, fonts containing characters with no
width or height would not render any more. 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.

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 : 5.5
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
