Red Hat: 2015:1668-01: httpd: Moderate Advisory
Summary
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.
