Hi,
The following vulnerability was published for jackd2.
CVE-2019-13351[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
