Amazon Linux AMI : php (ALAS-2012-37)

Medium Nessus Plugin ID 69644

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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)

Solution

Run 'yum update php' to update your system.
