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 2.1.
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 denial of service flaw was found in the way PHP processed a deeply nested array. A remote attacker could cause the PHP interpreter to crash by submitting an input variable with a deeply nested array.
A flaw was found in the way PHP's unserialize() function processes data. If a remote attacker is able to pass arbitrary data to PHP's unserialize() function, it may be possible for them to execute arbitrary code as the apache user. (CVE-2007-1286)
A double free flaw was found in PHP's session_decode() function. If a remote attacker is able to pass arbitrary data to PHP's session_decode() function, it may be possible for them to execute arbitrary code as the apache user. (CVE-2007-1711)
Users of PHP should upgrade to these updated packages which contain backported patches to correct these issues.
SolutionUpdate the affected packages.
