| summary: Memory exhaustion in QUIC connection handling in crypto/tls |
| description: |- |
| 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. |
