Synopsis: Moderate: php53 and php security update
Issue Date: 2012-01-11
CVE Numbers: CVE-2011-4885
 CVE-2011-4566

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)

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.
