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

high Nessus Plugin ID 21054

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 Hakkinen 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)

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.
