|Gentoo Linux Security Advisory
Title: GraphicsMagick: PALM and DCM buffer overflows (GLSA 200611-07)
Date: November 13, 2006
GraphicsMagick improperly handles PALM and DCM images, potentially
resulting in the execution of arbitrary code.
GraphicsMagick is a collection of tools and libraries which support
reading, writing, and manipulating images in many major formats.
Vulnerable: < 1.1.7-r3
Unaffected: >= 1.1.7-r3
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All GraphicsMagick users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7-r3"
