Ubuntu Security Notice USN-3939-2
April 08, 2019

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

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

- Ubuntu 12.04 ESM

Summary:

Samba could be made to create files in unexpected locations.

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

Details:

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

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