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