NVD Description

Note: Versions mentioned in the description apply only to the upstream curl-7.69.1 package and not the curl-7.69.1 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can continuously stream empty datagrams to indefinitely stall the client.
