CVE-2020-12658 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

gssproxy (aka gss-proxy) before 0.8.3 does not unlock cond_mutex before pthread exit in gp_worker_main() in gp_workers.c. NOTE: An upstream comment states "We are already on a shutdown path when running the code in question, so a DoS there doesn't make any sense, and there has been no additional information provided us (as upstream) to indicate why this would be a problem.
