Detail

Problem Description:

Updated php53 and php packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

3. Description:

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 Wälde 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.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

750547 - CVE-2011-4885 php: hash table collisions CPU usage DoS (oCERT-2011-003) 758413 - CVE-2011-4566 php: integer overflow in exif_process_IFD_TAG() may lead to DoS or arbitrary memory disclosure
