| Doc Text: |
A flaw was found in curl and libcurl. A malicious HTTP/3 server can exploit an issue in the QUIC UDP receive function by continuously streaming empty UDP datagrams. This can lead to a remote denial of service (DoS) against a curl or libcurl client, as the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, causing the client to indefinitely stall.
