Synopsis ========
Multiple vulnerabilities in the Apache HTTP daemon allow for local privilege escalation, information disclosure or Denial of Service attacks.
Background ==========
The Apache HTTP server is one of the most popular web servers on the Internet.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/apache < 2.2.11-r2 >=3D 2.2.11-r2
Description ===========
Multiple vulnerabilities have been discovered in the Apache HTTP server:
* Jonathan Peatfield reported that the "Options=3DIncludesNoEXEC" 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", "mod_proxy_ajp", "mod_proxy_http" and "deflate" from APACHE2_MODULES in make.conf and rebuild Apache, or disable the aforementioned modules in the Apache configuration.
Resolution ==========
All Apache users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dwww-servers/apache-2.2.11-r2"
