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...

Astra Linux – Vulnerability in curl

When an application instructs libcurl to enable HTTP/2 server push, and the number of received headers for the push exceeds the maximum allowed limit 1000, libcurl abends the server push. During this process, libcurl inadvertently does not free all of the previously allocated headers; instead, it...
