    John Fitzpatrick of MWR InfoSecurity discovered an authentication bypass
    vulnerability in torque, a PBS-derived batch processing queueing system.
    
    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.
