"USN-3298-1 fixed a vulnerability in MiniUPnP. This update provides the
corresponding update for Ubuntu 17.04.

It was discovered that MiniUPnP incorrectly handled memory. A remote
attacker could use this issue to cause a denial of service or possibly
execute arbitrary code with privileges of the user running an
application that uses the MiniUPnP library.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
