  "summary": "WITHDRAWN: Pre-protocol error reader permits unbounded memory consumption in github.com/lib/pq",
  "details": "(This report has been withdrawn with reason: \"Report mistakenly added without having CVE / GHSA associated\"). The special-case parser for PostgreSQL pre-protocol plain-text errors in github.com/lib/pq calls bufio.Reader.ReadString(0) without a byte limit. A malicious PostgreSQL endpoint or active network attacker on an unauthenticated transport can send an error message response with non-NUL bytes continuously, causing the client to buffer an arbitrarily large string and crash with an unrecoverable out-of-memory error.",
