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

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. 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.

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
