CVE-2016-1579: UDM doesn't check for confinement before running post-processing commands

First published: Mon Apr 22 2019(Updated: )

UDM provides support for running commands after a download is completed, this is currently made use of for click package installation. This functionality was not restricted to unconfined applications. Before UDM version 1.2+16.04.20160408-0ubuntu1 any confined application could make use of the UDM C++ API to run arbitrary commands in an unconfined environment as the phablet user.
