It is recommended that administrators running libntlm check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Package : libntlm Version : 1.4-3+deb8u1 CVE ID : CVE-2019-17455 It was discovered that 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. For Debian 8 "Jessie", this problem has been fixed in version 1.4-3+deb8u1. We recommend that you upgrade your libntlm packages.
