USN-7-1: imagemagick vulnerability

27 October 2004

imagemagick vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10

Software Description

Details

A buffer overflow in imagemagick’s EXIF parsing routine has been discovered in imagemagick versions prior to 6.1.0. Trying to query EXIF information of a malicious image file 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 4.10
libmagick6

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
