[GLSA]

Gentoo Linux Security Advisory

Title: GraphicsMagick: PALM and DCM buffer overflows (GLSA 200611-07)
Severity: normal
Exploitable: remote
Date: November 13, 2006
Bug(s): #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: media-gfx/graphicsmagick
Vulnerable: < 1.1.7-r3
Unaffected: >= 1.1.7-r3
Architectures: 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:
