It was announced just yesterday that there's a new-and-serious Samba bug. Information about it can be found here:
"In CVE-2017-7494, a malicious client can "upload a shared library to a writable share, and then cause the server to load and execute it.""
On my 16.04 LTS server, I ran 'samba --version" and got back: 4.3.11
When I followed the link in the article to Samba's website, it indicates fixes for some versions, but not for Samba 4.3.11. Does anyone know when Ubuntu/Canonical will be making an update for Samba available to us?
