Summary

Memory exhaustion in QUIC connection handling in crypto/tls

Details

QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth.

With fix, connections now consistently reject messages larger than 65KiB in size.
