## Description

pngrtran.c in libpng 1.5.x before 1.5.1 allows remote attackers to cause a
denial of service (application crash) or possibly execute arbitrary code
via a crafted palette-based PNG image that triggers a buffer overflow,
related to the png\_do\_expand\_palette function, the png\_do\_rgb\_to\_gray
function, and an integer underflow. NOTE: some of these details are
obtained from third party information.
