USN-7-1: imagemagick vulnerability

Publication date

27 October 2004

Overview

imagemagick vulnerability

Releases

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.
