Synopsis :

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

Description :

From Red Hat Security Advisory 2014:1327 :

Updated php packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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.

A buffer overflow flaw was found in the way the File Information
(fileinfo) extension processed certain Pascal strings. A remote
attacker able to make a PHP application using fileinfo convert a
specially crafted Pascal string provided by an image file could cause
that application to crash. (CVE-2014-3478)

Multiple flaws were found in the File Information (fileinfo) extension
regular expression rules for detecting various files. A remote
attacker could use either of these flaws to cause a PHP application
using fileinfo to consume an excessive amount of CPU. (CVE-2014-3538)

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)

It was found that PHP's gd extension did not properly handle file
names with a null character. A remote attacker could possibly use this
flaw to make a PHP application access unexpected files and bypass
intended file system access restrictions. (CVE-2014-5120)

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-2014-3478 issue was discovered by Francisco Alonso of Red Hat
Product Security, the CVE-2014-3538 issue was discovered by Jan
Kaluza of the Red Hat Web Stack Team, and the CVE-2014-3597 issue was
discovered by David Kutalek of the Red Hat BaseOS QE.

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.
