github.com/lib/pq allocates the backend-declared PostgreSQL frame payload before applying a protocol length bound or a phase-specific message-type check. A malicious server or active network attacker on an unauthenticated connection can send frame headers declaring multi-gigabyte or invalid-phase payloads, forcing large allocations that lead to memory exhaustion and runtime out-of-memory crashes.
