SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 5.
This update has been rated as having important 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 way the mbstring extension set global variables. A script which used the mb_parse_str() function to set global variables could be forced to enable the register_globals configuration option, possibly resulting in global variable injection.
A heap based buffer overflow flaw was discovered in PHP's gd extension. A script that could be forced to process WBMP images from an untrusted source could result in arbitrary code execution.
A buffer over-read flaw was discovered in PHP's gd extension. A script that could be forced to write arbitrary string using a JIS font from an untrusted source could cause the PHP interpreter to crash.
A flaw was discovered in the way PHP's mail() function processed header data. If a script sent mail using a Subject header containing a string from an untrusted source, a remote attacker could send bulk e-mail to unintended recipients. (CVE-2007-1718)
Users of PHP should upgrade to these updated packages which contain backported patches to correct these issues.
SolutionUpdate the affected packages.
