https://notcve.org/view.php?id=CVE-2011-4415
The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607. La función ap_pregsub en server/util.c en el servidor HTTP Apache v2.0.x hasta la 2.0.64 y la v2.2.x hasta la v2.2.21, cuando el módulo mod_setenvif está activado, no limita el tamaño de los valores de las variables de entorno, lo que permite a usuarios locales causar una denegación de servicio (consumo de memoria o puntero a NULL) a través de un archivo de tipo .htaccess que incluye una directiva SetEnvIf modificada, junto con un encabezado de solicitud HTTP manipulado, relacionado con (1) la declarción "len + =" y (2) con la llamada a la funcion apr_pcalloc, una vulnerabilidad diferente a CVE-2011-3607. • https://www.exploit-db.com/exploits/41769 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://www.gossamer-threads.com/lists/apache/dev/403775 http://www.halfdog.net/Security/2011/ApacheModSetEnvIfIntegerOverflow http://www.halfdog.net/Security/2011/ApacheModSetEnvIfIntegerOverflow/DemoExploit.html • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2011-3368
The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character. El módulo mod_proxy del servidor HTTP Apache 1.3.x hasta la versión 1.3.42, 2.0.x hasta la 2.0.64 y 2.2.x hasta la 2.2.21 no interactúa apropiadamente con el uso de coincidencias de patrones de (1) RewriteRule y (2) ProxyPassMatch para la configuración de proxys inversos, lo que permite a atacantes remotos enviar peticiones a servidores de intranet a través de URIs malformadas que contengan un carácter inicial @ (arroba). Context discovered a security vulnerability which allows for Apache in reverse proxy mode to be used to access internal/DMZ systems due to a weakness in its handling of URLs being processed by mod_rewrite. Versions 1.3 and 2.x are affected. • https://www.exploit-db.com/exploits/17969 https://github.com/SECFORCE/CVE-2011-3368 https://github.com/colorblindpentester/CVE-2011-3368 http://kb.juniper.net/JSA10585 http://lists.apple.com/archives/security-announce/2012/Sep/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2011-11/msg00011.html http://lists.opensuse.org/opensuse-updates/2013-02/msg00009.html http://lists.opensuse.org/opensuse-updates/2013-02/msg00012.html http://marc.info/?l=bugtraq&m=133294460209 • CWE-20: Improper Input Validation •
