USN-3411-1: Bazaar vulnerability

Releases

• Ubuntu 17.04
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• 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

• bzr - 2.7.0-2ubuntu3.1
• python-bzrlib - 2.7.0-2ubuntu3.1

Ubuntu 14.04

• 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.
