Gentoo Linux Security Advisory
Title: ImageMagick: PSD decoding heap overflow (GLSA 200501-26)
Severity: normal
Exploitable: remote
Date: January 20, 2005
Bug(s): #77932
ID: 200501-26
Synopsis
ImageMagick is vulnerable to a heap overflow when decoding Photoshop Document (PSD) files, which could lead to arbitrary code execution.
Background
ImageMagick is a collection of tools to read, write and manipulate images in many formats.
Affected Packages
Package: media-gfx/imagemagick
Vulnerable: < 6.1.8.8
Unaffected: >= 6.1.8.8
Architectures: All supported architectures
Description
Andrei Nigmatulin discovered that a Photoshop Document (PSD) file with more than 24 layers could trigger a heap overflow.
Impact
An attacker could potentially design a mailicous PSD image file to cause arbitrary code execution with the permissions of the user running ImageMagick.
Workaround
There is no known workaround at this time.
Resolution
All ImageMagick users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.1.8.8" |
