Memory leak in the winnt_accept function in server/mpm/winnt/child.c in the WinNT MPM in the Apache HTTP Server 2.4.x before 2.4.10 on Windows, when the default AcceptFilter is enabled, allows remote attackers to cause a denial of service (memory consumption) via crafted requests. Fuga de memoria en la función winnt_accept en server/mpm/winnt/child.c en el MPM WinNT en Apache HTTP Server 2.4.x anterior a 2.4.10 en Windows, cuando el AcceptFilter por defecto está habilitado, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de solicitudes manipuladas. • http://httpd.apache.org/security/vulnerabilities_24.html http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://rhn.redhat.com/errata/RHSA-2016-2957.html http://svn.apache.org/viewvc/httpd/httpd/trunk/server/mpm/winnt/child.c http://svn.apache.org/viewvc/httpd/httpd/trunk/server/mpm/winnt/child.c?r1=1608785&r2=1610652&diff_format=h http://www.securityfocus.com/bid/68747 https://lists.apache.org/thread.html/56c2 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2013-4352
The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value. La función cache_invalidate en modules/cache/cache_storage.c en el módulo mod_cache en Apache HTTP Server 2.4.6, cuando un proxy del cacheo de reenvíos está habilitado, permite a servidores HTTP remotos causar una denegación de servicio (referencia a puntero nulo y caída del demonio) a través de vectores que provocan un valor de nombre de anfitrión ausente. A NULL pointer dereference flaw was found in the mod_cache httpd module. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP Server was used as a forward proxy with caching. • http://httpd.apache.org/security/vulnerabilities_24.html http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/cache/cache_storage.c http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/cache/cache_storage.c?r1=1491564&r2=1523235&diff_format=h https://bugzilla.redhat.com/show_bug.cgi?id=1120604 https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd& • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2014-0117
The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header. El módulo mod_proxy en Apache HTTP Server 2.4.x anterior a 2.4.10, cuando un proxy inverso está habilitado, permite a atacantes remotos causar una denegación de servicio (caída del proceso hijo) a través de una cabecera de conexión HTTP manipulada. A denial of service flaw was found in the mod_proxy httpd module. A remote attacker could send a specially crafted request to a server configured as a reverse proxy using a threaded Multi-Processing Modules (MPM) that would cause the httpd child process to crash. This vulnerability allows remote attackers to cause a denial of service condition on vulnerable installations of Apache HTTP Server. • http://advisories.mageia.org/MGASA-2014-0305.html http://httpd.apache.org/security/vulnerabilities_24.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://seclists.org/fulldisclosure/2014/Jul/117 http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/proxy/mod_proxy_http.c http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/proxy/mod_proxy_http.c?r1=1599486&r2=1610674&diff_format=h http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/proxy/ • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-0226
Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c. Condición de carrera en el módulo mod_status en Apache HTTP Server anterior a 2.4.10 permite a atacantes remotos causar una denegación de servicio (desbordamiento de buffer basado en memoria dinámica), o posiblemente obtener información sensible de credenciales o ejecutar código arbitrario, a través de una solicitud manipulada que provoca el manejo indebido de la tabla de clasificación (scoreboard) dentro de la función status_handler en modules/generators/mod_status.c y la función lua_ap_scoreboard_worker en modules/lua/lua_request.c. A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the "apache" user. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache HTTPD server. • https://www.exploit-db.com/exploits/34133 https://github.com/shreesh1/CVE-2014-0226-poc http://advisories.mageia.org/MGASA-2014-0304.html http://advisories.mageia.org/MGASA-2014-0305.html http://httpd.apache.org/security/vulnerabilities_24.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://marc.info/?l=bugtraq&m=143403519711434&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http&# • CWE-122: Heap-based Buffer Overflow CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2013-5704
The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass "RequestHeader unset" directives by placing a header in the trailer portion of data sent with chunked transfer coding. NOTE: the vendor states "this is not a security issue in httpd as such." El módulo mod_headers en el servidor de Apache HTTP 2.2.22 permite a atacantes remotos evadir directivas "RequestHeader unset" mediante la colocación de una cabera en la porción "trailer" de datos enviados con codificación de transferencia fragmentada. NOTA: el proveedor afirma que "esto no es un problema de seguridad en httpd como tal." A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. • http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00004.html http://marc.info/?l=apache-httpd-dev&m=139636309822854&w=2 http://marc.info/?l=bugtraq&m=143403519711434&w=2 http://marc.info/?l=bugtraq&m=144493176821532&w=2 http://martin.swende.se/blog/HTTPChunked.html http://rhn.redhat.com/errata/RHSA-2015-0325.html http://rhn.redhat.com/errata/RHSA-2015-1249.html http://rhn.redhat& • CWE-287: Improper Authentication •
