    Patch CVE-2024-2398
  7. Configuration

    If you do not require HTTP/2 server push, do not allow it in your libcurl configuration to avoid the memory leak/DoS condition described for CVE-2024-2398.

    libcurl (HTTP/2 server push) HTTP/2 server push allowance (allow server push) = disable (do not allow HTTP/2 server push)
  8. Compensating control

    If you allow HTTP/2 server push, enforce/limit the number of received headers for PUSH_PROMISE to the maximum allowed limit (1000) so libcurl aborts the server push instead of leaking memory.
