Title:	RedHat Update for php53 and php RHSA-2012:0019-01
Summary:	The remote host is missing an update for the 'php53 and php'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'php53 and php' package(s) announced via the referenced advisory. Vulnerability Insight: PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. It was found that the hashing routine used by PHP arrays was susceptible to predictable hash collisions. If an HTTP POST request to a PHP application contained many parameters whose names map to the same hash value, a large amount of CPU time would be consumed. This flaw has been mitigated by adding a new configuration directive, max_input_vars, that limits the maximum number of parameters processed per request. By default, max_input_vars is set to 1000. (CVE-2011-4885) An integer overflow flaw was found in the PHP exif extension. On 32-bit systems, a specially-crafted image file could cause the PHP interpreter to crash or disclose portions of its memory when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-4566) Red Hat would like to thank oCERT for reporting CVE-2011-4885. oCERT acknowledges Julian Wlde and Alexander Klink as the original reporters of CVE-2011-4885. All php53 and php users should upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect. Affected Software/OS: php53 and php on Red Hat Enterprise Linux (v. 5 server) Solution: Please Install the Updated Packages. CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:P
