                   Red Hat Security Advisory

Synopsis:          Moderate: httpd security update
Advisory ID:       RHSA-2012:0323-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-0323.html
Issue date:        2012-02-21
CVE Names:         CVE-2011-3607 CVE-2011-3639 CVE-2012-0031 
                   CVE-2012-0053 
=====================================================================

1. Summary:

Updated httpd 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
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The Apache HTTP Server is a popular web server.

It was discovered that the fix for CVE-2011-3368 (released via
RHSA-2011:1392) did not completely address the problem. An attacker could
bypass the fix and make a reverse proxy connect to an arbitrary server not
directly accessible to the attacker by sending an HTTP version 0.9 request.
(CVE-2011-3639)

The httpd server included the full HTTP header line in the default error
page generated when receiving an excessively long or malformed header.
Malicious JavaScript running in the server's domain context could use this
flaw to gain access to httpOnly cookies. (CVE-2012-0053)

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way httpd performed substitutions in regular expressions. An
attacker able to set certain httpd settings, such as a user permitted to
override the httpd configuration for a specific directory using a
".htaccess" file, could use this flaw to crash the httpd child process or,
possibly, execute arbitrary code with the privileges of the "apache" user.
(CVE-2011-3607)

A flaw was found in the way httpd handled child process status information.
A malicious program running with httpd child process privileges (such as a
PHP or CGI script) could use this flaw to cause the parent httpd process to
crash during httpd service shutdown. (CVE-2012-0031)

All httpd users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the httpd daemon will be restarted automatically.

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/kb/docs/DOC-11259
