The Apache HTTP server is one of the most popular web servers on the

Internet.

|
|
Multiple vulnerabilities have been discovered in the Apache HTTP
|
|
server:
|
|
</p>
|
|
<ul>
|
|
<li>Jonathan Peatfield reported that the
|
|
"Options=IncludesNoEXEC" argument to the "AllowOverride" directive is
|
|
not processed properly (CVE-2009-1195).</li>
|
|
<li>Sander de Boer
|
|
discovered that the AJP proxy module (mod_proxy_ajp) does not correctly
|
|
handle POST requests that do not contain a request body
|
|
(CVE-2009-1191).</li>
|
|
<li>The vendor reported that the HTTP proxy
|
|
module (mod_proxy_http), when being used as a reverse proxy, does not
|
|
properly handle requests containing more data as stated in the
|
|
"Content-Length" header (CVE-2009-1890).</li>
|
|
<li>Francois Guerraz
|
|
discovered that mod_deflate does not abort the compression of large
|
|
files even when the requesting connection is closed prematurely
|
|
(CVE-2009-1891).</li>
|
|
</ul>

<impact type="high">
|
|
<p>
|
|
A local attacker could circumvent restrictions put up by the server
|
|
administrator and execute arbitrary commands with the privileges of the
|
|
user running the Apache server. A remote attacker could send multiple
|
|
requests to a server with the AJP proxy module, possibly resulting in
|
|
the disclosure of a request intended for another client, or cause a
|
|
Denial of Service by sending specially crafted requests to servers
|
|
running mod_proxy_http or mod_deflate.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Remove "include", "proxy_ajp", "proxy_http" and "deflate" from
|
|
APACHE2_MODULES in make.conf and rebuild Apache, or disable the
|
|
aforementioned modules in the Apache configuration.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Apache users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.11-r2"</code>
|
|
</resolution>
