The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to improper resource shutdown or release in the execution timeout watcher when handling execution requests with a configured timeout. A remote user can submit code that ignores or catches SIGALRM to cause a denial of service.
The issue occurs because the timeout mechanism sends SIGALRM instead of the uncatchable SIGKILL signal.
