GLSA-200907-04 : Apache: Multiple vulnerabilities

High Nessus Plugin ID 39775

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200907-04 (Apache: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in the Apache HTTP server:
Jonathan Peatfield reported that the 'Options=IncludesNoEXEC' argument to the 'AllowOverride' directive is not processed properly (CVE-2009-1195).
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).
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).
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).
Impact :

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.
Workaround :

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.

Solution

All Apache users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/apache-2.2.11-r2'
