| <p> |
| The Apache HTTP server is one of the most popular web servers on the |
| Internet. |
| </p> |
| </background> |
| <description> |
| <p> |
| Multiple vulnerabilities have been discovered in the Apache HTTP |
| server: |
| </p> |
| <ul> |
| <li>Jonathan Peatfield reported that the |
| "Options=IncludesNoEXEC" argument to the "AllowOverride" directive is |
| not processed properly (CVE-2009-1195).</li> |
| <li>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).</li> |
| <li>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).</li> |
| <li>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).</li> |
| </ul> |
| </description> |
| <impact type="high"> |
| <p> |
| 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. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| 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. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Apache users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.11-r2"</code> |
| </resolution> |
