"From Red Hat Security Advisory 2015:0325 :

Updated httpd packages that fix two security issues, several bugs, and
add various enhancements are for Red Hat Enterprise Linux 7.

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.

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

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)

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)

This update also fixes the following bugs :

* Previously, the mod_proxy_fcgi Apache module always kept the
back-end connections open even when they should have been closed. As a
consequence, the number of open file descriptors was increasing over
the time. With this update, mod_proxy_fcgi has been fixed to check the
state of the back-end connections, and it closes the idle back-end
connections as expected. (BZ#1168050)

* An integer overflow occurred in the ab utility when a large request
count was used. Consequently, ab terminated unexpectedly with a
segmentation fault while printing statistics after the benchmark. This
bug has been fixed, and ab no longer crashes in this scenario.
(BZ#1092420)

* Previously, when httpd was running in the foreground and the user
pressed Ctrl+C to interrupt the httpd processes, a race condition in
signal handling occurred. The SIGINT signal was sent to all children
followed by SIGTERM from the main process, which interrupted the
SIGINT handler. Consequently, the affected processes became
unresponsive or terminated unexpectedly. With this update, the SIGINT
signals in the child processes are ignored, and httpd no longer hangs
or crashes in this scenario. (BZ#1131006)

In addition, this update adds the following enhancements :

* With this update, the mod_proxy module of the Apache HTTP Server
supports the Unix Domain Sockets (UDS). This allows mod_proxy back
ends to listen on UDS sockets instead of TCP sockets, and as a result,
mod_proxy can be used to connect UDS back ends. (BZ#1168081)

* This update adds support for using the SetHandler directive together
with the mod_proxy module. As a result, it is possible to configure
SetHandler to use proxy for incoming requests, for example, in the
following format: SetHandler 'proxy:fcgi://127.0.0.1:9000'.
(BZ#1136290)

* The htaccess API changes introduced in httpd 2.4.7 have been
backported to httpd shipped with Red Hat Enterprise Linux 7.1. These
changes allow for the MPM-ITK module to be compiled as an httpd
module. (BZ#1059143)

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

"According to its banner, the version of Apache 2.4.x running on the
remote host is prior to 2.4.12. It is, therefore, affected by the
following vulnerabilities :

  - A flaw exists in module mod_headers that can allow HTTP
    trailers to replace HTTP headers late during request
    processing, which a remote attacker can exploit to
    inject arbitrary headers. This can also cause some
    modules to function incorrectly or appear to function
    incorrectly. (CVE-2013-5704)

  - A NULL pointer dereference flaw exists in module
    mod_cache. A remote attacker, using an empty HTTP
    Content-Type header, can exploit this vulnerability to
    crash a caching forward proxy configuration, resulting
    in a denial of service if using a threaded MPM.
    (CVE-2014-3581)

  - A out-of-bounds memory read flaw exists in module
    mod_proxy_fcgi. An attacker, using a remote FastCGI
    server to send long response headers, can exploit this
    vulnerability to cause a denial of service by causing
    a buffer over-read. (CVE-2014-3583)

  - A flaw exists in module mod_lua when handling a
    LuaAuthzProvider used in multiple Require directives
    with different arguments. An attacker can exploit this
    vulnerability to bypass intended access restrictions.

"Updated apache packages fix security vulnerabilities :

Apache HTTPD before 2.4.9 was vulnerable to a denial of service in
mod_dav when handling DAV_WRITE requests (CVE-2013-6438).

Apache HTTPD before 2.4.9 was vulnerable to a denial of service when
logging cookies (CVE-2014-0098).

A race condition flaw, leading to heap-based buffer overflows, was
found in the mod_status httpd module. A remote attacker able to access
a status page served by mod_status on a server using a threaded
Multi-Processing Module (MPM) could send a specially crafted request
that would cause the httpd child process to crash or, possibly, allow
the attacker to execute arbitrary code with the privileges of the
apache user (CVE-2014-0226).

A denial of service flaw was found in the mod_proxy httpd module. A
remote attacker could send a specially crafted request to a server
configured as a reverse proxy using a threaded Multi-Processing
Modules (MPM) that would cause the httpd child process to crash
(CVE-2014-0117).

A denial of service flaw was found in the way httpd's mod_deflate
module handled request body decompression (configured via the DEFLATE
input filter). A remote attacker able to send a request whose body
would be decompressed could use this flaw to consume an excessive
amount of system memory and CPU on the target system (CVE-2014-0118).

A denial of service flaw was found in the way httpd's mod_cgid module
executed CGI scripts that did not read data from the standard input. A
remote attacker could submit a specially crafted request that would
cause the httpd child process to hang indefinitely (CVE-2014-0231).

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).

mod_lua.c in the mod_lua module in the Apache HTTP Server through
2.4.10 does not support an httpd configuration in which the same Lua
authorization provider is used with different arguments within
different contexts, which allows remote attackers to bypass intended
access restrictions in opportunistic circumstances by leveraging
multiple Require directives, as demonstrated by a configuration that
specifies authorization for one group to access a certain directory,
and authorization for a second group to access a second directory
(CVE-2014-8109).

In the mod_lua module in the Apache HTTP Server through 2.4.10, a
maliciously crafted websockets PING after a script calls r:wsupgrade()
can cause a child process crash (CVE-2015-0228).

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
(rhbz#1141950)."

"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)

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)

This update also fixes the following bugs :

  - Previously, the mod_proxy_fcgi Apache module always kept
    the back-end connections open even when they should have
    been closed. As a consequence, the number of open file
    descriptors was increasing over the time. With this
    update, mod_proxy_fcgi has been fixed to check the state
    of the back- end connections, and it closes the idle
    back-end connections as expected.

  - An integer overflow occurred in the ab utility when a
    large request count was used. Consequently, ab
    terminated unexpectedly with a segmentation fault while
    printing statistics after the benchmark. This bug has
    been fixed, and ab no longer crashes in this scenario.

  - Previously, when httpd was running in the foreground and
    the user pressed Ctrl+C to interrupt the httpd
    processes, a race condition in signal handling occurred.
    The SIGINT signal was sent to all children followed by
    SIGTERM from the main process, which interrupted the
    SIGINT handler. Consequently, the affected processes
    became unresponsive or terminated unexpectedly. With
    this update, the SIGINT signals in the child processes
    are ignored, and httpd no longer hangs or crashes in
    this scenario.

In addition, this update adds the following enhancements :

  - With this update, the mod_proxy module of the Apache
    HTTP Server supports the Unix Domain Sockets (UDS). This
    allows mod_proxy back ends to listen on UDS sockets
    instead of TCP sockets, and as a result, mod_proxy can
    be used to connect UDS back ends.

  - This update adds support for using the SetHandler
    directive together with the mod_proxy module. As a
    result, it is possible to configure SetHandler to use
    proxy for incoming requests, for example, in the
    following format: SetHandler
    'proxy:fcgi://127.0.0.1:9000'.

  - The htaccess API changes introduced in httpd 2.4.7 have
    been backported to httpd shipped with Scientific Linux
    7.1. These changes allow for the MPM-ITK module to be
    compiled as an httpd module.

After installing the updated packages, the httpd daemon will be
restarted automatically."

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.

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

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,

"The Apache2 webserver was updated to fix various issues.

The following feature was added :

  - Provide support for the tunneling of web socket
    connections to a backend websockets server.
    (FATE#316880) The following security issues have been
    fixed :

  - The mod_headers module in the Apache HTTP Server 2.2.22
    allowed remote attackers to bypass 'RequestHeader unset'
    directives by placing a header in the trailer portion of
    data sent with chunked transfer coding. The fix also
    adds a 'MergeTrailers' directive to restore legacy
    behavior. (CVE-2013-5704)

  - The cache_merge_headers_out function in
    modules/cache/cache_util.c in the mod_cache module in
    the Apache HTTP Server allowed remote attackers to cause
    a denial of service (NULL pointer dereference and
    application crash) via an empty HTTP Content-Type
    header. (CVE-2014-3581)

  - Apache HTTP Server allowed remote attackers to obtain
    sensitive information via (1) the ETag header, which
    reveals the inode number, or (2) multipart MIME
    boundary, which reveals child process IDs (PID). We so
    far assumed that this not useful to attackers, the fix
    is basically just reducing potential information leaks.
    (CVE-2003-1418)

The following bugs have been fixed :

  - Treat the 'server unavailable' condition as a transient
    error with all LDAP SDKs. (bsc#904427)

  - Fixed a segmentation fault at startup if the certs are
    shared across > 1 server_rec. (bsc#907339)"
