Synopsis:          Moderate: php53 security update
Advisory ID:       RHSA-2011:0196-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2011:0196.html
Issue date:        2011-02-03

====================================================================
1. Summary:

Updated php53 packages that fix three 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.

A flaw was found in the way PHP converted certain floating point values
from string representation to a number. If a PHP script evaluated an
attacker's input in a numeric context, the PHP interpreter could cause high
CPU usage until the script execution time limit is reached. This issue only
affected i386 systems. (CVE-2010-4645)

A stack memory exhaustion flaw was found in the way the PHP filter_var()
function validated email addresses. An attacker could use this flaw to
crash the PHP interpreter by providing excessively long input to be
validated as an email address. (CVE-2010-3710)

A memory disclosure flaw was found in the PHP multi-byte string extension.
If the mb_strcut() function was called with a length argument exceeding the
input string size, the function could disclose a portion of the PHP
interpreter's memory. (CVE-2010-4156)

All php53 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
