Security issues fixed: CVE-2013-5704: Added a change to fix a flaw in
the way mod_headers handled chunked requests. Adds 'MergeTrailers'
directive to restore legacy behavior [bnc#871310],

CVE-2014-8109: Fixes handling of the Require line when a
LuaAuthzProvider is used in multiple Require directives with different
arguments.

Bugfixes :

  - changed apache2.service file to fix situation where
    apache won't start at boot when using an encrypted
    certificate because user isn't prompted for password
    during boot [bnc#792309].

  - added <IfModule> around SSLSessionCache to avoid failing

    incorrectly. (CVE-2013-5704)

    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.

  - 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

"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)."

  script_set_attribute(attribute:"description", value:
"According to the versions of the httpd packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - A vulnerability was found in Apache HTTP Server 2.4.0
    to 2.4.38. When the path component of a request URL
    contains multiple consecutive slashes ('/'), directives
    such as LocationMatch and RewriteRule must account for
    duplicates in regular expressions while other aspects
    of the servers processing will implicitly collapse
    them.(CVE-2019-0220)

  - A specially crafted request could have crashed the
    Apache HTTP Server prior to version 2.4.30, due to an
    out of bound access after a size limit is reached by
    reading the HTTP header. This vulnerability is
    considered very hard if not impossible to trigger in
    non-debug mode (both log and build level), so it is
    classified as low risk for common server
    usage.(CVE-2018-1301)

  - In Apache httpd 2.4.0 to 2.4.29, when mod_session is
    configured to forward its session data to CGI
    applications (SessionEnv on, not the default), a remote
    user may influence their content by using a 'Session'
    header. This comes from the 'HTTP_SESSION' variable
    name used by mod_session to forward its data to CGIs,
    since the prefix 'HTTP_' is also used by the Apache
    HTTP Server to pass HTTP header fields, per CGI
    specifications.(CVE-2018-1283)

  - mod_lua.c in the mod_lua module in the Apache HTTP
    Server 2.3.x and 2.4.x 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)

description block directly from the EulerOS security advisory. Tenable
