Ubuntu Security Notice USN-3092-1
September 28, 2016

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

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

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Samba could be tricked into connecting to impersonated servers.

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

Details:

Stefan Metzmacher discovered that Samba incorrectly handled certain flags
in SMB2/3 client connections. A remote attacker could use this issue to
disable client signing and impersonate servers by performing a man in the
middle attack.

Samba has been updated to 4.3.11 in Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
In addition to the security fix, the updated packages contain bug fixes,
new features, and possibly incompatible changes.

Update instructions:

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

Ubuntu 16.04 LTS:
samba 2:4.3.11+dfsg-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
samba 2:4.3.11+dfsg-0ubuntu0.14.04.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
