GLSA-200611-07 : GraphicsMagick: PALM and DCM buffer overflows
Medium Nessus Plugin ID 23672
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200611-07 (GraphicsMagick: PALM and DCM buffer overflows)
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.
SolutionAll GraphicsMagick users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/graphicsmagick-1.1.7-r3'
