SYSTEMS AFFECTED

  WinNT
  

PROBLEM


    Applications can set their  own priority level, which  affects how
    often Windows NT allows those applications to run. An  application
    running under  a user  account with  administrative privileges can
    set  its  priority  to  any  of  32 levels, with the highest level
    giving it  more time  slices. Applications  running under accounts
    without administrative  privileges can  set their  priority to any
    of the first 16 of those levels.

    CpuHog sets its priority to the highest level available, which  is
    level 16 when run  by a normal user.  Windows NT attempts to  deal
    with CPU-hogging  applications by  boosting the  priority of other
    applications. However, Windows NT will only boost applications  as
    high  as  level  15.  Thus,  all  other applications - even system
    utilities such  as Task  Manager -  never get  a chance to execute
    while  CpuHog  is  running.   CpuHog  program  can  be  found   at
    www.ntinternals.com.   Credit for  discovery of  this bug  goes to

EXPLOIT

  

SOLUTION


    Give Task Manager level 16.  In that way You will be able to  kill
    hogging process.
