Severity: Normal Title: ImageMagick: PALM and DCM buffer overflows Date: November 24, 2006 Bugs: #152672 ID: 200611-19

Synopsis ========
ImageMagick improperly handles PALM and DCM images, potentially resulting in the execution of arbitrary code.
Background ==========
ImageMagick is a software suite to create, edit, and compose bitmap images, that can also read, write, and convert images in many other formats.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/imagemagick < 6.3.0.5 >= 6.3.0.5
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 ImageMagick, and possibly execute arbitrary code with the privileges of the user running ImageMagick.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ImageMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.0.5"
