Mandriva Linux Security Advisory 2009:285: php

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,

Additionally on CS4 a regression was found and fixed when using the
gd-bundled.so variant from the php-gd package.

This update fixes these vulnerabilities...
