CVE-2018-11763 – Apache2 mod_http2 header Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-11763
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento del tiempo de conexión. Esto solo afecta a las conexiones HTTP/2. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105414 http://www.securitytracker.com/id/1041713 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7f • CWE-20: Improper Input Validation •

CVE-2014-0226 – Apache httpd mod_status Heap Buffer Overflow Remote Code Execution Vulnerability
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') •
CVE-2013-5704 – httpd: bypass of mod_headers rules via chunked requests
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 •
CVE-2014-0098 – httpd: mod_log_config does not properly handle logging certain cookies resulting in DoS
https://notcve.org/view.php?id=CVE-2014-0098
The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server before 2.4.8 allows remote attackers to cause a denial of service (segmentation fault and daemon crash) via a crafted cookie that is not properly handled during truncation. La función log_cookie en mod_log_config.c en el módulo mod_log_config en el Apache HTTP Server anterior a 2.4.8 permite a atacantes remotos causar una denegación de servicio (fallo de segmentación y caída de demonio) a través de una cookie manipulada que no es manejada debidamente durante truncado. • http://advisories.mageia.org/MGASA-2014-0135.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0101.html http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10698 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://marc.info/?l=bugtraq&m=141017844705317&w=2 http://marc.info/?l=bugtraq&m=141390017113542&w=2 http://seclists.org/fulldisclosure/2014/Dec/23 http://secunia.com/advisories/58230 http://secunia.com/advisories/58915 http: • CWE-125: Out-of-bounds Read •
