USN-3562-1: MiniUPnP vulnerabilities

7 February 2018

MiniUPnP could be made to crash or run programs if it received specially crafted network traffic.



  • miniupnpc - UPnP IGD client lightweight library


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 17.10
Ubuntu 16.04
Ubuntu 14.04

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