Package        : samba
CVE ID         : CVE-2017-12150 CVE-2017-12151 CVE-2017-12163

Multiple security issues have been discoverd in Samba, a SMB/CIFS file,
print, and login server for Unix:

CVE-2017-12150

    Stefan Metzmacher discovered multiple code paths where SMB signing
    was not enforced.

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 oldstable distribution (jessie), these problems have been fixed
in version 2:4.2.14+dfsg-0+deb8u8.

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.
