CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 1CVE-2019-10081 – httpd: memory corruption on early pushes
https://notcve.org/view.php?id=CVE-2019-10081
HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. Pushes tempranos de HTTP/2 (versiones 2.4.20 hasta 2.4.39) configurados por ejemplo con "H2PushResource", podrían conllevar a una sobrescritura de memoria en el pushing de grupo de peticiones causando bloqueos. La memoria copiada es la de los valores configurados de encabezado del enlace de inserción, no los datos suministrados por el cliente. A vulnerability was found in Apache httpd, in mod_http2. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00004.html https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/r03ee478b3dda3e381fd6189366fa7af97c980d2f602846eef935277d%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r3c5c3104813c1c5508b55564b66546933079250a46ce50eee90b2e36%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/r76142b8c5119df2178be7c2dba88 • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 3%CPEs: 43EXPL: 0CVE-2019-9517 – Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service
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 •
