CVE-2020-9490 – httpd: Push diary crash on specifically crafted HTTP/2 header
https://notcve.org/view.php?id=CVE-2020-9490
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43.. Un valor especialmente diseñado para el encabezado "Cache-Digest" en una petición HTTP/2 resultaría en un bloqueo cuando el servidor realmente intenta un PUSH HTTP/2 un recurso mas tarde. • 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/160392/Apache-2.4.43-mod_http2-Memory-Corruption.html https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2020-9490 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') •
