Summary:
Samba could be made to expose sensitive information over the network.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
Details:
Stefan Metzmacher discovered that Samba incorrectly enforced SMB signing in certain situations. A remote attacker could use this issue to perform a man in the middle attack. (CVE-2017-12150)
Stefan Metzmacher discovered that Samba incorrectly handled encryption across DFS redirects. A remote attacker could use this issue to perform a man in the middle attack. (CVE-2017-12151)

The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.04: samba 2:4.5.8+dfsg-0ubuntu0.17.04.7
