https://notcve.org/view.php?id=CVE-2019-9517
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. Algunas implementaciones HTTP / 2 son vulnerables al almacenamiento en búfer de datos interal sin restricciones, lo que puede conducir a una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://www.openwall.com/lists/oss-security/2019/08/15/7 https://access.redhat.com/errata/RHSA-2019:2893 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2946 https:/ • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2019-0197
A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue. Una vulnerabilidad fue encontrada en Apache HTTP Server 2.4.34 hasta 2.4.38 y clasificada como problemática. Cuando se habilitó HTTP / 2 para un http: host o H2Upgrade se habilitó para h2 en un https: host, una solicitud de actualización de http / 1.1 a http / 2 que no fue la primera solicitud en una conexión podría provocar una mala configuración y un fallo. • 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/2019/04/02/2 http://www.securityfocus.com/bid/107665 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://httpd.apac • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions. En Apache HTTP Server 2.4, versiones 2.4.37 y 2.4.38, un error en mod_ssl al utilizar la verificación de certificados de cliente por ubicación con TLSv1.3 permitía a un cliente eludir las restricciones de control de acceso configuradas. A flaw was found in Apache HTTP Server 2.4 (releases 2.4.37 and 2.4.38). A bug in mod_ssl, when using per-location client certificate verification with TLSv1.3, allowed a client supporting Post-Handshake Authentication to bypass configured access control restrictions. An attacker could perform various unauthorized actions after bypassing the restrictions. • http://www.openwall.com/lists/oss-security/2019/04/02/4 http://www.securityfocus.com/bid/107667 https://access.redhat.com/errata/RHSA-2019:0980 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/117bc3f09847ebf020b1bb70301ebcc105ddc446856150b63f37f8eb%40%3Cdev.httpd.apache.org%3E https://lists.apache.org/thread.html/2d6bd429a0ba9af1580da896575cfca6e42bb05e7536562d4b095fcf%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40% • CWE-284: Improper Access Control •
