[GLSA]

Gentoo Linux Security Advisory

Title: GraphicsMagick: PSD decoding heap overflow (GLSA 200501-37)
Severity: normal
Exploitable: remote
Date: January 26, 2005
Bug(s): #79336
ID: 200501-37

Synopsis


GraphicsMagick is vulnerable to a heap overflow when decoding Photoshop
Document (PSD) files, which could lead to arbitrary code execution.


Background


GraphicsMagick is a collection of tools to read, write and
manipulate images in many formats. GraphicsMagick is originally derived
from ImageMagick 5.5.2.


Affected Packages

Package: media-gfx/graphicsmagick
Vulnerable: < 1.1.5
Unaffected: >= 1.1.5
Architectures: All supported architectures


Description


Andrei Nigmatulin discovered that handling a Photoshop Document
(PSD) file with more than 24 layers in ImageMagick could trigger a heap
overflow (GLSA 200501-26). GraphicsMagick is based on the same code and
therefore suffers from the same flaw.


Impact


An attacker could potentially design a malicious PSD image file to
cause arbitrary code execution with the permissions of the user running
GraphicsMagick.


Workaround


There is no known workaround at this time.


Resolution


All GraphicsMagick users should upgrade to the latest version:
