Multiple vulnerabilities has been found and corrected in php: 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 (CVE-2009-3546). Added two upstream patches to address a bypass vulnerability in open_basedir and safe_mode. 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. Affected: 2009.0, 2009.1, Corporate 3.0, Corporate 4.0, Enterprise Server 5.0, Multi Network Firewall 2.0
