https://notcve.org/view.php?id=CVE-2019-10082
In Apache HTTP Server 2.4.18-2.4.39, using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown. En Apache HTTP Server versiones 2.4.18 hasta 2.4.39, usando la entrada de red difusa, el manejo de la sesión http/2 podría ser hecha para leer la memoria después de ser liberada, durante el apagado de la conexión. A read-after-free vulnerability was discovered in Apache httpd, in mod_http2. A specially crafted http/2 client session could cause the server to read memory that was previously freed during connection shutdown, potentially leading to a crash. • 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/r76142b8c5119df2178be7c2dba88fde552eedeec37ea993dfce68d1d%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2019-10098
In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL. En el servidor HTTP Apache versiones 2.4.0 hasta 2.4.39, los Redireccionamientos configurados con mod_rewrite que fueron previstos a estar auto referenciados podrían ser engañados por nuevas líneas codificadas y redireccionadas a una URL inesperada dentro de la URL de la petición. A vulnerability was discovered in Apache httpd, in mod_rewrite. Certain self-referential mod_rewrite rules could be fooled by encoded newlines, causing them to redirect to an unexpected location. An attacker could abuse this flaw in a phishing attack or as part of a client-side attack on browsers. • https://www.exploit-db.com/exploits/47689 http://www.openwall.com/lists/oss-security/2020/04/01/4 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.apac • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

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.

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 •
