*Hello Team *
I Keyur Maheta found security issue in your system {HIGH}
severity: high
description: Apache HTTP Server versions 2.4.20 to 2.4.43 are
susceptible to a denial of service attack. 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.
