CVE-2009-3546
The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.0, and the
GD Graphics Library 2.x, does not properly verify a certain
colorsTotal structure member, which might allow remote attackers to
conduct buffer overflow or buffer over-read attacks via a crafted GD
file, a different vulnerability than CVE-2009-3293.  NOTE: some of
these details are obtained from third party information.");
