Several vulnerabilities have been found in the Apache HTTPD Server: CVE-2011-3607: An integer overflow in ap_pregsub could allow local attackers to execute arbitrary code at elevated privileges via crafted .htaccess files. CVE-2011-3368 CVE-2011-3639 CVE-2011-4317: The Apache HTTP Server did not properly validate the request URI for proxied requests. In certain reverse proxy configurations using the ProxyPassMatch directive or using the RewriteRule directive with the [P] flag, a remote attacker could make the proxy connect to an arbitrary server. The could allow the attacker to access internal servers that are not otherwise accessible from the outside. The three CVE ids denote slightly different variants of the same issue. Note that, even with this issue fixed, it is the responsibility of the administrator to ensure that the regular expression replacement pattern for the target URI does not allow a client to append arbitrary strings to the host or port parts of the target URI. This is a violation of the privilege separation between the apache2 processes and could potentially be used to worsen the impact of other vulnerabilities. CVE-2012-0053: The response message for error code 400 could be used to expose "httpOnly" cookies. This could allow a remote attacker using cross site scripting to steal authentication cookies.
