Matt Ezell from Oak Ridge National Labs reported a vulnerability in torque, a PBS-derived batch processing queueing system.

A user could submit executable shell commands on the tail of what is passed with the -M switch for qsub. This was later passed to a pipe, making it possible for these commands to be executed as root on the pbs_server.
