USN-35-1: imagemagick vulnerabilities

imagemagick vulnerabilities

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

  • Ubuntu 4.10

Software Description

Details

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.

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.
