The torque authentication model revolves around the use of privileged ports. If a request is not made from a privileged port then it is assumed not to be trusted or authenticated. It was found that pbs_mom does not perform a check to ensure that connections are established from a privileged port. A user who can run jobs or login to a node running pbs_server or pbs_mom can exploit this vulnerability to remotely execute code as root on the cluster by submitting a command directly to a pbs_mom daemon to queue and run a job. For the oldstable distribution (squeeze), this problem has been fixed in version 2.4.8+dfsg-9squeeze2. For the stable distribution (wheezy), this problem has been fixed in version 2.4.16+dfsg-1+deb7u1. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your torque packages.
