Adam Collard discovered that Bazaar did not properly handle host names
in 'bzr+ssh://' URLs. A remote attacker could use this to construct
a bazaar repository URL that when accessed could run arbitrary code
with the privileges of the user.

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

Ubuntu 17.04
Ubuntu 16.04
Ubuntu 14.04

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