Comment 2 for bug 1783591

For Ubuntu specifically:
 - precise: unaffected (0.7.5 or 1.0.9)
 - trusty: unaffected (1.0.10 or 2.0.8)
 - xenial: backports only (2.0.8 or 3.0.1)
 - bionic: affected (3.0.1)
 - cosmic: affected (3.0.1)

The 2.0 branch is only affected starting with 2.0.8, as we never pushed that bugfix release to Ubuntu, we're not affected for the series that include this version.
