Updated httpd packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

The httpd packages provide the Apache HTTP Server, a powerful, efficient,
and extensible web server.

Multiple flaws were found in the way httpd parsed HTTP requests and
responses using chunked transfer encoding. A remote attacker could use
these flaws to create a specially crafted request, which httpd would decode
differently from an HTTP proxy software in front of it, possibly leading to
HTTP request smuggling attacks. (CVE-2015-3183)

All httpd users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
updated packages, the httpd service will be restarted automatically.
