Subject: tm_adopt() vulnerability in TORQUE Resource Manager

Within a TORQUE Resource Manager job, the tm_adopt() TORQUE library call
enables a user-built executable calling tm_adopt() to adopt any session id
(and its child processes) regardless of the session id owner on any node
within a job. When a job that includes the executable calling tm_adopt()
exits, the adopted processes are killed along with the job processes during
normal job cleanup. This can enable a non-root user to kill processes
he/she doesn't own including root-owned ones on any node in a job.

The issue has been fixed in the following commit numbers for the listed
TORQUE Resource Manager versions:
