    CVE-2019-13351

    Summary: Updated jackit packages fix security vulnerability

    Details: posix/JackSocket.cpp in libjack in JACK2 1.9.1 through 1.9.12 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 (CVE-2019-13351).
