Low: httpd24

Issue Overview:

Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE (CVE-2020-11984)

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. A flaw was found in Apache httpd in versions prior to 2.4.46. A specially crafted Cache-Digest header triggers negative argument to memmove() that could lead to a crash and denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-9490)

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. (CVE-2020-11993)
