                   Red Hat Security Advisory

Synopsis:          Moderate: php security update
Advisory ID:       RHSA-2012:1045-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-1045.html
Issue date:        2012-06-27
CVE Names:         CVE-2011-4153 CVE-2012-0057 CVE-2012-0789 
                   CVE-2012-1172 CVE-2012-2336 
=====================================================================

1. Summary:

Updated php packages that fix multiple security issues 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 discovered that the PHP XSL extension did not restrict the file
writing capability of libxslt. A remote attacker could use this flaw to
create or overwrite an arbitrary file that is writable by the user running
PHP, if a PHP script processed untrusted eXtensible Style Sheet Language
Transformations (XSLT) content. (CVE-2012-0057)

Note: This update disables file writing by default. A new PHP configuration
directive, "xsl.security_prefs", can be used to enable file writing in
XSLT.

A flaw was found in the way PHP validated file names in file upload
requests. A remote attacker could possibly use this flaw to bypass the
sanitization of the uploaded file names, and cause a PHP script to store
the uploaded file in an unexpected directory, by using a directory
traversal attack. (CVE-2012-1172)

It was discovered that the fix for CVE-2012-1823, released via
RHSA-2012:0546, did not properly filter all php-cgi command line arguments.
A specially-crafted request to a PHP script could cause the PHP interpreter
to output usage information that triggers an Internal Server Error.
(CVE-2012-2336)

A memory leak flaw was found in the PHP strtotime() function call. A remote
attacker could possibly use this flaw to cause excessive memory consumption
by triggering many strtotime() function calls. (CVE-2012-0789)

It was found that PHP did not check the zend_strndup() function's return
value in certain cases. A remote attacker could possibly use this flaw to
crash a PHP application. (CVE-2011-4153)

All php users should upgrade to these updated packages, which contain
backported patches to resolve 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.

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/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

782657 - CVE-2012-0057 php: XSLT file writing vulnerability
782943 - CVE-2011-4153 php: zend_strndup() NULL pointer dereference may cause DoS
783609 - CVE-2012-0789 php: strtotime timezone memory leak
799187 - CVE-2012-1172 php: $_FILES array indexes corruption
820708 - CVE-2012-2336 php: incomplete CVE-2012-1823 fix - missing filtering of -T and -h
