Subject: [USN-90-1] Imagemagick vulnerability

===========================================================
Ubuntu Security Notice USN-90-1		     March 03, 2005
imagemagick vulnerability
CAN-2005-0397
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

imagemagick
libmagick6

The problem can be corrected by upgrading the affected package to
version 5:6.0.2.5-1ubuntu1.4.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Tavis Ormandy discovered a format string vulnerability in ImageMagick's file
name handling. Specially crafted file names could cause a program using
ImageMagick to crash, or possibly even cause execution of arbitrary code.

Since ImageMagick can be used in custom printing systems, this also might lead
to privilege escalation (execute code with the printer spooler's privileges).
However, Ubuntu's standard printing system does not use ImageMagick, thus there
is no risk of privilege escalation in a standard installation.

ImageMagick is also commonly used by web frontends; if these accept image
uploads with arbitrary file names, this could also lead to remote privilege
escalation.
