(RHSA-2014:1326) Moderate: php53 and php security update

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server. PHP’s fileinfo module provides functions used to identify a
particular file according to the type of data contained by the file.

It was found that the fix for CVE-2012-1571 was incomplete; the File
Information (fileinfo) extension did not correctly parse certain Composite
Document Format (CDF) files. A remote attacker could use this flaw to crash
a PHP application using fileinfo via a specially crafted CDF file.
(CVE-2014-3587)

A NULL pointer dereference flaw was found in the gdImageCreateFromXpm()
function of PHP’s gd extension. A remote attacker could use this flaw to
crash a PHP application using gd via a specially crafted X PixMap (XPM)
file. (CVE-2014-2497)

Multiple buffer over-read flaws were found in the php_parserr() function of
PHP. A malicious DNS server or a man-in-the-middle attacker could possibly
use this flaw to execute arbitrary code as the PHP interpreter if a PHP
application used the dns_get_record() function to perform a DNS query.
(CVE-2014-3597)

Two use-after-free flaws were found in the way PHP handled certain Standard
PHP Library (SPL) Iterators and ArrayIterators. A malicious script author
could possibly use either of these flaws to disclose certain portions of
server memory. (CVE-2014-4670, CVE-2014-4698)

The CVE-2014-3597 issue was discovered by David Kutalek of the Red Hat
BaseOS QE.

All php53 and 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.
