Scientific Linux Security Update : php on SL4.x i386/x86_64 (20120130)

medium Nessus Plugin ID 61227

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

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)

An insufficient input validation flaw, leading to a buffer over-read, was found in the PHP exif extension. A specially crafted image file could cause the PHP interpreter to crash when a PHP script tries to extract Exchangeable image file format (Exif) metadata from the image file. (CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote attacker able to make a PHP script call SdnToJulian() with a large value could cause the PHP interpreter to crash. (CVE-2011-1466)

An off-by-one flaw was found in PHP. If an attacker uploaded a file with a specially crafted file name it could cause a PHP script to attempt to write a file to the root (/) directory. By default, PHP runs as the 'apache' user, preventing it from writing to the root directory. (CVE-2011-2202)

All 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.

Solution

Update the affected packages.
