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

USN-3939-1 fixed a vulnerability in Samba. This update provides
the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

 Michael Hanselmann discovered that Samba incorrectly handled registry
 files. A remote attacker could possibly use this issue to create new
 registry files outside of the share, contrary to expectations.

Update instructions:

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

Ubuntu 12.04 ESM:
  libsmbclient                    2:3.6.25-0ubuntu0.12.04.17
  samba                           2:3.6.25-0ubuntu0.12.04.17
