-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Low: httpd24-httpd security and bug fix update Advisory ID: RHSA-2014:1972-01 Product: Red Hat Software Collections Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1972.html Issue date: 2014-12-09 CVE Names: CVE-2013-5704 CVE-2014-3581 ===================================================================== 1. Summary: Updated httpd24-httpd packages that fix two security issues and one bug are now available for Red Hat Software Collections 1. Red Hat Product Security has rated this update as having Low 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: Red Hat Software Collections 1 for Red Hat Enterprise Linux Server (v. 6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server (v. 7) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.4) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.5) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Server EUS (v. 6.6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Workstation (v. 6) - noarch, x86_64 Red Hat Software Collections 1 for Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 3. Description: The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. A NULL pointer dereference flaw was found in the way the mod_cache httpd module handled Content-Type headers. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP server was configured to proxy to a server with caching enabled. (CVE-2014-3581) A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) Note: With this update, httpd has been modified to not merge HTTP Trailer headers with other HTTP request headers. A newly introduced configuration directive MergeTrailers can be used to re-enable the old method of processing Trailer headers, which also re-introduces the aforementioned flaw. This update also fixes the following bug: * Prior to this update, the mod_proxy_wstunnel module failed to set up an SSL connection when configured to use a back end server using the "wss:" URL scheme, causing proxied connections to fail. In these updated packages, SSL is used when proxying to "wss:" back end servers. (BZ#1141950) All httpd24-httpd users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd24-httpd service 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.
