    An issue was discovered in the codec. A hash collision vulnerability (in the hash map used to manage connections) allows remote attackers to cause a considerable CPU load on the server (a Hash DoS attack) by initiating connections with colliding Source Connection IDs (SCIDs). See https://github.com/ncc-pbottine/QUIC-Hash-Dos-Advisory

    Recommended action: Upgrade to 0.0.71.Final or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
