CVE-2012-1499

9.3 HIGH 5% exploit odds No fix listed Memory safety

What it is

The JPEG 2000 codec (jp2.c) in OpenJPEG before 1.5 allows remote attackers to execute arbitrary code via a crafted palette index in a CMAP record of a JPEG image, which triggers memory corruption, aka "out-of heap-based buffer write."
