https://notcve.org/view.php?id=CVE-2020-11993
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43, cuando trace/debug fue habilitado para el módulo HTTP/2 y en determinados patrones de tráfico de borde, se hicieron declaraciones de registro en la conexión errónea, causando un uso concurrente de grupos de memoria. Configurando el LogLevel de mod_http2 sobre "info" mitigará esta vulnerabilidad para los servidores sin parches A flaw was found in Apache httpd in versions 2.4.20 to 2.4.43. Logging using the wrong pool by mod_http2 at debug/trace log level may lead to potential crashes and denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00081.html http://packetstormsecurity.com/files/160393/Apache-2-HTTP2-Module-Concurrent-Pool-Usage.html https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2020-11993 https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E https://lists&# • CWE-400: Uncontrolled Resource Consumption CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
