3. Description:

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server.

A flaw was found in the way the PHP module for the Apache httpd web server
handled pipelined requests. A remote attacker could use this flaw to
trigger the execution of a PHP script in a deinitialized interpreter,
causing it to crash or, possibly, execute arbitrary code. (CVE-2015-3330)

A flaw was found in the way PHP parsed multipart HTTP POST requests. A
specially crafted request could cause PHP to use an excessive amount of CPU
time. (CVE-2015-4024)

An uninitialized pointer use flaw was found in PHP’s Exif extension. A
specially crafted JPEG or TIFF file could cause a PHP application using the
exif_read_data() function to crash or, possibly, execute arbitrary code
with the privileges of the user running that PHP application.
(CVE-2015-0232)

An integer overflow flaw leading to a heap-based buffer overflow was found
in the way PHP’s FTP extension parsed file listing FTP server responses. A
malicious FTP server could use this flaw to cause a PHP application to
crash or, possibly, execute arbitrary code. (CVE-2015-4022)

Multiple flaws were discovered in the way PHP performed object
unserialization. Specially crafted input processed by the unserialize()
function could cause a PHP application to crash or, possibly, execute
arbitrary code. (CVE-2014-8142, CVE-2015-0231, CVE-2015-0273,
CVE-2015-2787, CVE-2015-4147, CVE-2015-4148, CVE-2015-4599, CVE-2015-4600,
CVE-2015-4601, CVE-2015-4602, CVE-2015-4603)

It was found that certain PHP functions did not properly handle file names
containing a NULL character. A remote attacker could possibly use this flaw
to make a PHP script access unexpected files and bypass intended file
system access restrictions. (CVE-2015-2348, CVE-2015-4025, CVE-2015-4026,
CVE-2015-3411, CVE-2015-3412, CVE-2015-4598)

Multiple flaws were found in the way the way PHP’s Phar extension parsed
Phar archives. A specially crafted archive could cause PHP to crash or,
possibly, execute arbitrary code when opened. (CVE-2015-2301,
CVE-2015-2783, CVE-2015-3307, CVE-2015-3329, CVE-2015-4021)

Multiple flaws were found in PHP’s File Information (fileinfo) extension.
A remote attacker could cause a PHP application to crash if it used
fileinfo to identify type of attacker supplied files. (CVE-2014-9652,
CVE-2015-4604, CVE-2015-4605)

A heap buffer overflow flaw was found in the enchant_broker_request_dict()
function of PHP’s enchant extension. An attacker able to make a PHP
application enchant dictionaries could possibly cause it to crash.
(CVE-2014-9705)

A buffer over-read flaw was found in the GD library used by the PHP gd
extension. A specially crafted GIF file could cause a PHP application using
the imagecreatefromgif() function to crash. (CVE-2014-9709)

This update also fixes the following bugs:

* The libgmp library in some cases terminated unexpectedly with a
segmentation fault when being used with other libraries that use the GMP
memory management. With this update, PHP no longer changes libgmp memory
allocators, which prevents the described crash from occurring. (BZ#1212305)

* When using the Open Database Connectivity (ODBC) API, the PHP process
in some cases terminated unexpectedly with a segmentation fault. The
underlying code has been adjusted to prevent this crash. (BZ#1212299)

* Previously, running PHP on a big-endian system sometimes led to memory
corruption in the fileinfo module. This update adjusts the behavior of
the PHP pointer so that it can be freed without causing memory corruption.
(BZ#1212298)

All php users are advised to upgrade to these updated packages, which
contain backported patches to correct 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.
