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:
- 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).
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"
