Ubuntu 4.10 / 5.04 / 5.10 : imagemagick vulnerabilities (USN-246-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Florian Weimer discovered that the delegate code did not correctly
handle file names which embed shell commands (CVE-2005-4601). Daniel
Kobras found a format string vulnerability in the SetImageInfo()
function (CVE-2006-0082). By tricking a user into processing an image
file with a specially crafted file name, these two vulnerabilities
could be exploited to execute arbitrary commands with the user's
privileges. These vulnerability become particularly critical if
malicious images are sent as email attachments and the email client
uses imagemagick to convert/display the images (e. g. Thunderbird and
Gnus).

In addition, Eero H�inen reported a bug in the command line argument
processing of the 'display' command. Arguments that contained
wildcards and were expanded to several files could trigger a heap
overflow. However, there is no known possiblity to exploit this
remotely. (http://bugs.debian.org/345595)

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)
