Updated samba packages has been released for Debian 7 LTS

Package : samba
Version : 2:3.6.6-6+deb7u12
CVE ID : CVE-2017-2619

Jann Horn of Google discovered a time-of-check, time-of-use race
condition in Samba, a SMB/CIFS file, print, and login server for Unix. A
malicious client can take advantage of this flaw by exploting a symlink
race to access areas of the server file system not exported under a
share definition.

For Debian 7 "Wheezy", these problems have been fixed in version
2:3.6.6-6+deb7u12.

We recommend that you upgrade your samba packages.
