Astra Linux – Vulnerability in Apache2

In certain proxy configurations, a denial-of-service attack against Apache HTTP Server versions 2.4.26 through 2.4.63 can occur when untrusted clients trigger an assertion in modproxyhttp2. The configurations affected include reverse proxies configured for HTTP/2 backends, where ProxyPreserveHost...
