CVE-2019-17455 not yet assigned priority: Debian including 1 source packages (libntlm), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.
