Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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

The Red Hat Security Response Team 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 denial of service flaw was found in the File Information (fileinfo)
extension rules for detecting AWK files. A remote attacker could use
this flaw to cause a PHP application using fileinfo to consume an
excessive amount of CPU. (CVE-2013-7345)

Multiple denial of service flaws were found in the way the File
Information (fileinfo) extension parsed certain Composite Document
Format (CDF) files. A remote attacker could use either of these flaws
to crash a PHP application using fileinfo via a specially crafted CDF
file. (CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479,
CVE-2014-3480, CVE-2014-3487)

A heap-based buffer overflow flaw was found in the way PHP parsed DNS
TXT records. 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-2014-4049)

A type confusion issue was found in PHP's phpinfo() function. A
malicious script author could possibly use this flaw to disclose
certain portions of server memory. (CVE-2014-4721)

A type confusion issue was found in the SPL ArrayObject and
SPLObjectStorage classes' unserialize() method. A remote attacker able
to submit specially crafted input to a PHP application, which would
then unserialize this input using one of the aforementioned methods,
could use this flaw to execute arbitrary code with the privileges of
the user running that PHP application. (CVE-2014-3515)

The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479,
CVE-2014-3480, and CVE-2014-3487 issues were discovered by Francisco
Alonso of Red Hat Product Security.

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.
