Upgrade Ubuntu:16.04 jackd2 to version 1.9.10+20150825git1ed50c92~dfsg-1ubuntu1+esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream jackd2 package and not the jackd2 package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
posix/JackSocket.cpp in libjack in JACK2 1.9.1 through 1.9.12 (as distributed with alsa-plugins 1.1.7 and later) has a "double file descriptor close" issue during a failed connection attempt when jackd2 is not running. Exploitation success depends on multithreaded timing of that double close, which can result in unintended information disclosure, crashes, or file corruption due to having the wrong file associated with the file descriptor.
