Description: 
 The perfmonctl system call (sys_perfmonctl) in Linux kernel 2.4.x and
 2.6 before 2.6.18, when running on Itanium systems, does not properly
 track the reference count for file descriptors, which allows local
 users to cause a denial of service (file descriptor consumption).
Ubuntu-Description:
Notes:
 dannf> I don't think 2.4 is affected - there are no existing calls to fput
