CESA-2006:0567: php security update

Description

Updated PHP packages that fix multiple security issues are now available for CentOS Linux 2.1 This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server. A flaw was found in the zend_hash_del() PHP function. For PHP scripts that rely on the use of the unset() function, a remote attacker could force variable initialization to be bypassed. This would be a security issue particularly for installations that enable the "register_globals" setting. "register_globals" is disabled by default in CentOS Linux. (CVE-2006-3017) A directory traversal vulnerability was found in PHP. Local users could bypass open_basedir restrictions allowing remote attackers to create files in arbitrary directories via the tempnam() function. (CVE-2006-1494) A flaw was found in the PHP IMAP MIME header decoding function. An attacker could craft a message with an overly long header which caused PHP to crash. (CVE-2002-2214) Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.
