Synopsis
The remote CentOS host is missing one or more security updates.
Description
Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.
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.
Various integer overflow flaws were found in the PHP gd extension. A script that could be forced to resize images from an untrusted source could possibly allow a remote attacker to execute arbitrary code as the apache user. (CVE-2007-3996)
An integer overflow flaw was found in the PHP chunk_split function. If a remote attacker was able to pass arbitrary data to the third argument of chunk_split they could possibly execute arbitrary code as the apache user. Note that it is unusual for a PHP script to use the chunk_script function with a user-supplied third argument.
(CVE-2007-2872)
A previous security update introduced a bug into PHP session cookie handling. This could allow an attacker to stop a victim from viewing a vulnerable website if the victim has first visited a malicious web page under the control of the attacker, and that page can set a cookie for the vulnerable website. (CVE-2007-4670)
A flaw was found in the PHP money_format function. If a remote attacker was able to pass arbitrary data to the money_format function this could possibly result in an information leak or denial of service. Note that is is unusual for a PHP script to pass user-supplied data to the money_format function. (CVE-2007-4658)
A flaw was found in the PHP wordwrap function. If a remote attacker was able to pass arbitrary data to the wordwrap function this could possibly result in a denial of service. (CVE-2007-3998)
A bug was found in PHP session cookie handling. This could allow an attacker to create a cross-site cookie insertion attack if a victim follows an untrusted carefully-crafted URL. (CVE-2007-3799)
An infinite-loop flaw was discovered in the PHP gd extension. A script that could be forced to process PNG images from an untrusted source could allow a remote attacker to cause a denial of service.
(CVE-2007-2756)
Users of PHP should upgrade to these updated packages, which contain backported patches to correct these issues.
