CVE-2009-0040
The PNG reference library (aka libpng) before 1.0.43, and 1.2.x before
1.2.35, as used in pngcrush and other applications, allows
context-dependent attackers to cause a denial of service (application
crash) or possibly execute arbitrary code via a crafted PNG file that
triggers a free of an uninitialized pointer in (1) the png_read_png
function, (2) pCAL chunk handling, or (3) setup of 16-bit gamma
tables.";
