=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04

Summary:
Git could be made run programs as your login if it opened a specially
crafted git repository.
Software Description:
- git: fast, scalable, distributed revision control system
Details:
Brian Neel, Joern Schneeweisz, and Jeff King discovered that Git did
not properly handle host names in 'ssh://' URLs. A remote attacker
could use this to construct a git repository that when accessed could
run arbitrary code with the privileges of the user.

package versions:
Ubuntu 17.04:

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