GO-2026-6173

>= 1.11.0
Description

(This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated").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.
