USN-62-1: imagemagick vulnerability

19 January 2005

imagemagick vulnerability

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

  • Ubuntu 4.10

Software Description


Andrei Nigmatulin discovered a potential buffer overflow in the PhotoShop Document image decoding function of ImageMagick. Decoding a malicious PSD image which specifies more than the allowed 24 channels 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

To update your system, please follow these instructions:
