More information:

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 exploiting a symlink race to access areas of the server file system not exported under a share definition.

For the stable distribution (jessie), this problem has been fixed in version 2:4.2.14+dfsg-0+deb8u4.

For the unstable distribution (sid), this problem has been fixed in version 2:4.5.6+dfsg-2.

We recommend that you upgrade your samba packages.
