php security update

CentOS Errata and Security Advisory CESA-2009:0337

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.

A heap-based buffer overflow flaw was found in PHP’s mbstring extension. A
remote attacker able to pass arbitrary input to a PHP script using mbstring
conversion functions could cause the PHP interpreter to crash or,
possibly, execute arbitrary code. (CVE-2008-5557)

A flaw was found in the handling of the “mbstring.func_overload”
configuration setting. A value set for one virtual host, or in a user’s
.htaccess file, was incorrectly applied to other virtual hosts on the same
server, causing the handling of multibyte character strings to not work
correctly. (CVE-2009-0754)

A buffer overflow flaw was found in PHP’s imageloadfont function. If a PHP
script allowed a remote attacker to load a carefully crafted font file, it
could cause the PHP interpreter to crash or, possibly, execute arbitrary
code. (CVE-2008-3658)

A flaw was found in the way PHP handled certain file extensions when
running in FastCGI mode. If the PHP interpreter was being executed via
FastCGI, a remote attacker could create a request which would cause the PHP
interpreter to crash. (CVE-2008-3660)

A memory disclosure flaw was found in the PHP gd extension’s imagerotate
function. A remote attacker able to pass arbitrary values as the
“background color” argument of the function could, possibly, view portions
of the PHP interpreter’s memory. (CVE-2008-5498)

All php users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues. The httpd web server
must be restarted for the changes to take effect.
