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> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1195">CVE-2009-1195</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1191">CVE-2009-1191</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1890">CVE-2009-1890</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1891">CVE-2009-1891</uri> </references> <metadata tag="requester" timestamp="2009-07-11T20:22:24Z"> a3li </metadata> <metadata tag="submitter" timestamp="2009-07-11T21:34:40Z"> a3li </metadata> <metadata tag="bugReady" timestamp="2009-07-12T15:17:06Z"> a3li </metadata> </glsa>
