there is a low-impact security issue in python-dbusmock, which is
described in detail on https://launchpad.net/bugs/1453815. I
originally prepared a stable-security upload, but the security team
(CC'ed Salvatore) asked this to be handled as a normal stable update
instead.
So I filed https://bugs.debian.org/786858 with a summary and proper
version tracking, and uploaded python-dbusmock 0.11.4-1+deb8u1 to
stable with the backported fix. This is fixed in 0.15.1-1 in
testing/unstable, oldstable does not have python-dbusmock.
