(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."
