RHEL 5 / 6 : php53 and php (RHSA-2012:0019)

high Nessus Plugin ID 57494

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for php53 / php.

Description

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0019 advisory.

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL php53 / php packages based on the guidance in RHSA-2012:0019.
