Summary

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), these problems have been fixed in
version 2:4.2.14+dfsg-0+deb8u5.

We recommend that you upgrade your samba packages.
