CVE-2017-12151 Stefan Metzmacher discovered that tools using libsmbclient did not enforce encryption when following DFS redirects, which could allow a man-in-the-middle attacker to read or modify connections which were meant to be encrypted. CVE-2017-12163 Yihan Lian and Zhibin Hu discovered that insufficient range checks in the processing of SMB1 write requests could result in disclosure of server memory.

For the stable distribution (stretch), these problems have been fixed in version 2:4.5.8+dfsg-2+deb9u2. We recommend that you upgrade your samba packages.
