Subject: pgpool: Fix pgproto buffer out of range access error.
Date: Tue, 15 Sep 2026 09:08:19 +0000
Message-ID: <E1x6P9H-00000004gHc-1sVV@gothos.postgresql.org> (raw)
Fix pgproto buffer out of range access error.
ASAN detected pgproto's buffer out of range access error. When it
tried to detect the continuation line (backslash + line feed), it
unconditionally access read buffer without checking the read length.
Fix is, adding buffer length check before accessing the buffer.
