Multiple heap-based buffer underflows in the ReadPALMImage function in coders/palm.c in GraphicsMagick before 1.2.3 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted PALM image, a different vulnerability than CVE-2007-0770. NOTE: some of these details are obtained from third party information.
