samba vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Samba could be made to expose sensitive information over the network.

Software Description:
- samba: SMB/CIFS file, print, and login server for Unix

Details:

Jann Horn discovered that Samba incorrectly handled symlinks. An
authenticated remote attacker could use this issue to access files on the
server outside of the exported directories.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.10:
samba 2:4.4.5+dfsg-2ubuntu5.4

Ubuntu 16.04 LTS:
samba 2:4.3.11+dfsg-0ubuntu0.16.04.5

Ubuntu 14.04 LTS:
samba 2:4.3.11+dfsg-0ubuntu0.14.04.6

Ubuntu 12.04 LTS:
samba 2:3.6.25-0ubuntu0.12.04.9

In general, a standard system update will make all the necessary changes.
