Description Vincent Danen 2013-11-05 15:56:09 UTC

The TORQUE pbs_server daemon was found to pass some user-input data to popen() in order to send an email.  Because pbs_server runs as root, this could allow an authenticated attacker to execute arbitrary code on the pbs_server host with root privileges.

The upstream 4.2.6 release corrects this flaw by forking and calling exec() to the sendmail program instead of passing the entire user-supplied string to popen().
