"From Red Hat Security Advisory 2015:1668 :

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."

"The Apache2 webserver was updated to fix several issues :

Security issues fixed :

  - The chunked transfer coding implementation in the Apache
    HTTP Server did not properly parse chunk headers, which
    allowed remote attackers to conduct HTTP request
    smuggling attacks via a crafted request, related to
    mishandling of large chunk-size values and invalid
    chunk-extension characters in
    modules/http/http_filters.c. [bsc#938728, CVE-2015-3183]

  - The LOGJAM security issue was addressed by: [bnc#931723
    CVE-2015-4000]

  - changing the SSLCipherSuite cipherstring to disable
    export cipher suites and deploy Ephemeral Elliptic-Curve
    Diffie-Hellman (ECDHE) ciphers.

  - Adjust 'gensslcert' script to generate a strong and
    unique Diffie Hellman Group and append it to the server
    certificate file.

  - The ap_some_auth_required function in server/request.c
    in the Apache HTTP Server 2.4.x did not consider that a
    Require directive may be associated with an
    authorization setting rather than an authentication
    setting, which allowed remote attackers to bypass
    intended access restrictions in opportunistic
    circumstances by leveraging the presence of a module
    that relies on the 2.2 API behavior. [bnc#938723
    bnc#939516 CVE-2015-3185]

  - Tomcat mod_jk information leak due to incorrect
    JkMount/JkUnmount directives processing [bnc#927845
    CVE-2014-8111]

Other bugs fixed :

  - Now provides a suse_maintenance_mmn_# [bnc#915666].

  - Hard-coded modules in the %files [bnc#444878].

  - Fixed the IfModule directive around SSLSessionCache
    [bnc#911159].

  - allow only TCP ports in Yast2 firewall files
    [bnc#931002]

  - fixed a regression when some LDAP searches or
    comparisons might be done with the wrong credentials
    when a backend connection is reused [bnc#930228]

  - Fixed split-logfile2 script [bnc#869790]

  - remove the changed MODULE_MAGIC_NUMBER_MINOR from which
    confuses modules the way that they expect functionality
    that our apache does not provide [bnc#915666]

  - gensslcert: CN now defaults to `hostname -f`
    [bnc#949766], fix help [bnc#949771]

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"Updated httpd and httpd22 packages that fix two security issues are
now available for Red Hat JBoss Web Server 2.1.0 for Red Hat
Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available from the
CVE links in the References section.

Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the
Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat
Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and
the Tomcat Native library.

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)

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)

Users of httpd or httpd22 are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue.
After installing the updated packages, the httpd or httpd22 service
must be restarted manually for this update to take effect."

"Updated httpd packages that fix two security issues are now available
for Red Hat Enterprise Linux 7.

Red Hat Product Security 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.

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)

It was discovered that in httpd 2.4, the internal API function
ap_some_auth_required() could incorrectly indicate that a request was
authenticated even when no authentication was used. An httpd module
using this API function could consequently allow access that should
have been denied. (CVE-2015-3185)

All httpd users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After
installing the updated packages, the httpd service will be restarted
automatically."
