|Gentoo Linux Security Advisory
Title: ImageMagick: PSD decoding heap overflow (GLSA 200501-26)
Date: January 20, 2005
ImageMagick is vulnerable to a heap overflow when decoding Photoshop Document (PSD) files, which could lead to arbitrary code execution.
ImageMagick is a collection of tools to read, write and manipulate images in many formats.
Vulnerable: < 18.104.22.168
Unaffected: >= 22.214.171.124
Architectures: All supported architectures
Andrei Nigmatulin discovered that a Photoshop Document (PSD) file with more than 24 layers could trigger a heap overflow.
An attacker could potentially design a mailicous PSD image file to cause arbitrary code execution with the permissions of the user running ImageMagick.
There is no known workaround at this time.
All ImageMagick users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-126.96.36.199"
