Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-q5pr-72pq-83v3. This link is maintained to preserve external references.
Original Description
h3 versions before 2.0.1-rc.18 fail to validate the chunk count parsed from user-controlled cookie values in setChunkedCookie() and deleteChunkedCookie() functions. Attackers can send a crafted cookie header with an extremely large chunk count to trigger an O(n²) cleanup loop that hangs the server process.
