Detail

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

- Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Bazaar could be made run programs as your login if it opened a specially crafted URL.

Software Description: - bzr: easy to use distributed version control system

Details:

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.

Update instructions:

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

Ubuntu 17.04:
bzr 2.7.0+bzr6619-7ubuntu0.1
python-bzrlib 2.7.0+bzr6619-7ubuntu0.1

Ubuntu 16.04 LTS:
bzr 2.7.0-2ubuntu3.1
python-bzrlib 2.7.0-2ubuntu3.1

Ubuntu 14.04 LTS:
bzr 2.6.0+bzr6593-1ubuntu1.6
python-bzrlib 2.6.0+bzr6593-1ubuntu1.6

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