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.
