GLSA 200611-07: GraphicsMagick: PALM and DCM buffer overflows

http://security.gentoo.org/

Severity:	normal
Title:	GraphicsMagick: PALM and DCM buffer overflows
Date:	11/13/2006
Bugs:	#152668
ID:	200611-07

Synopsis

GraphicsMagick improperly handles PALM and DCM images, potentially resulting in the execution of arbitrary code.

Background

GraphicsMagick is a collection of tools and libraries which support reading, writing, and manipulating images in many major formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/graphicsmagick	< 1.1.7-r3	>= 1.1.7-r3	All supported architectures

Description

M. Joonas Pihlaja has reported that a boundary error exists within the ReadDCMImage() function of coders/dcm.c, causing the improper handling of DCM images. Pihlaja also reported that there are several boundary errors in the ReadPALMImage() function of coders/palm.c, similarly causing the improper handling of PALM images.

Impact

An attacker could entice a user to open a specially crafted DCM or PALM image with GraphicsMagick, and possibly execute arbitrary code with the privileges of the user running GraphicsMagick.

Workaround

There is no known workaround at this time.

Resolution

All GraphicsMagick users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7-r3"
