Detail

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libmagick6

The problem can be corrected by upgrading the affected package to version 5:6.0.2.5-1ubuntu1.2. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Markus Meissner discovered several potential buffer overflows in some image decoding functions of ImageMagick. Decoding a malicious BMP or DIB image or AVI video might result in execution of arbitrary code with the user's privileges.

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.
