Description

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.
