CVE-2019-0196 – httpd: mod_http2: read-after-free on a string compare
https://notcve.org/view.php?id=CVE-2019-0196
A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly. Se descubrió una Vulnerabilidad en Apache HTTP Server 2.4.17. usando fuzzed network input, la http/2 manejo de solicitudes podría estar hechas para acceder a la memoria liberada en la comparación de cadenas al determinar el método de una solicitud y, por lo tanto, procesar la solicitud incorrectamente. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://www.apache.org/dist/httpd/CHANGES_2.4.39 http://www.openwall.com/lists/oss-security/2019/04/02/1 http://www.securityfocus.com/bid/107669 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://acces • CWE-416: Use After Free •
CVE-2019-0220 – httpd: URL normalization inconsistency
https://notcve.org/view.php?id=CVE-2019-0220
A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them. Se descubrió una vulnerabilidad en Apache HTTP Server 2.4.0 hasta 2.4.38. Cuando el componente del recorrido de la solicitud de la URL contiene múltiples barras diagonales consecutivas ('/'), como por ejemplo LocationMatch y RewriteRule debe tener en cuenta los duplicados en las expresiones regulares que otros aspectos del procesamiento de los servidores los colapsarán implícitamente. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://www.openwall.com/lists/oss-security/2019/04/02/6 http://www.securityfocus.com/bid/107670 https://access.redhat.com/errata/RHSA-2019:2343 https://access.redhat.com/errata/RHSA-2019:3436 https://access.redhat.com/errata/RHSA-2019:4126 https://access.red • CWE-41: Improper Resolution of Path Equivalence CWE-706: Use of Incorrectly-Resolved Name or Reference •
CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados. A flaw was found in Apache where code executing in a less-privileged child process or thread could execute arbitrary code with the privilege of the parent process (usually root). • https://www.exploit-db.com/exploits/46676 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://packetstormsecurity.com/files/152386/Apache-2.4.38-Root-Privilege-Escalation.html http://packetstormsecurity.com/files/152415/Slackware-Security-Advisory-httpd-Updates.html http://packetstormsecurity.com/files/152441/CARPE-DIEM-Apache-2.4.x • CWE-250: Execution with Unnecessary Privileges CWE-416: Use After Free •
CVE-2018-17189 – httpd: mod_http2: DoS via slow, unneeded request bodies
https://notcve.org/view.php?id=CVE-2018-17189
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. En Apache HTTP Server, en sus versiones 2.4.37 y anteriores, mediante el envío de cuerpos de respuesta mediante la técnica del "slow loris" a recursos planos, la transmisión h2 para esa petición ocupó de forma innecesaria un hilo de servidor que limpiaba tales datos entrantes. Esto afecta solo a las conexiones HTTP/2 (mod_http2). • http://www.securityfocus.com/bid/106685 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-17199 – httpd: mod_session_cookie does not respect expiry time
https://notcve.org/view.php?id=CVE-2018-17199
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. En Apache HTTP Server 2.4, en sus distribuciones 2.4.37 y anteriores, mod_session comprueba el tiempo de caducidad de la sesión antes de descodificarla. Esto provoca que se ignore el tiempo de caducidad de la sesión para sesiones mod_session_cookie, debido a que el tiempo de caducidad se carga cuando la sesión está descodificada. • http://www.securityfocus.com/bid/106742 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •
