CVE-2020-9490

Description

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.
