GraphicsMagick improperly handles PALM and DCM images, potentially resulting in the execution of arbitrary code.
|Package||media-gfx/graphicsmagick on all architectures|
|Affected versions||< 1.1.7-r3|
|Unaffected versions||>= 1.1.7-r3|
GraphicsMagick is a collection of tools and libraries which support reading, writing, and manipulating images in many major formats.
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"
