                   Red Hat Security Advisory

Synopsis:          Moderate: php53 security, bug fix and enhancement update
Advisory ID:       RHSA-2013:1307-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1307.html
Issue date:        2013-09-30
CVE Names:         CVE-2006-7243 CVE-2011-1398 CVE-2012-0831 
                   CVE-2012-2688 CVE-2013-1643 CVE-2013-4248 
=====================================================================

1. Summary:

Updated php53 packages that fix multiple security issues, several bugs, and
add one enhancement are now available for Red Hat Enterprise Linux 5.

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.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

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

It was found that PHP did not properly handle file names with 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-2006-7243)

It was found that PHP did not check for carriage returns in HTTP headers,
allowing intended HTTP response splitting protections to be bypassed.
Depending on the web browser the victim is using, a remote attacker could
use this flaw to perform HTTP response splitting attacks. (CVE-2011-1398)

A flaw was found in PHP's SSL client's hostname identity check when
handling certificates that contain hostnames with NULL bytes. If an
attacker was able to get a carefully crafted certificate signed by a
trusted Certificate Authority, the attacker could use the certificate to
conduct man-in-the-middle attacks to spoof SSL servers. (CVE-2013-4248)

An integer signedness issue, leading to a heap-based buffer underflow, was
found in the PHP scandir() function. If a remote attacker could upload an
excessively large number of files to a directory the scandir() function
runs on, it could cause the PHP interpreter to crash or, possibly, execute
arbitrary code. (CVE-2012-2688)

It was found that PHP did not correctly handle the magic_quotes_gpc
configuration directive. This could result in magic_quotes_gpc input
escaping not being applied in all cases, possibly making it easier for a
remote attacker to perform SQL injection attacks. (CVE-2012-0831)

It was found that the PHP SOAP parser allowed the expansion of external XML
entities during SOAP message parsing. A remote attacker could possibly use
this flaw to read arbitrary files that are accessible to a PHP application
using a SOAP extension. (CVE-2013-1643)

These updated php53 packages also include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 5.10 Technical
Notes, linked to in the References, for information on the most significant
of these changes.

All PHP users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues and add this
enhancement. 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.

This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258
