CVE-2020-11993: Push Diary Crash on Specifically Crafted HTTP/2 Header
Severity: moderate
Vendor: Apache Software Foundation
Versions Affected:
Apache HTTP Server 2.4.20 to 2.4.43
Description:
Apache HTTP Server versions 2.4.20 to 2.4.43
When trace/debug was enabled for the HTTP/2 module and on
certain traffic edge patterns, logging statements were made on
the wrong connection, causing concurrent use of memory pools.
Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
