Description Prasad J Pandit 2014-10-09 11:02:04 EDT 
Linux kernel built with the VFS and user name-space support(CONFIG_USER_NS) is vulnerable to a potential DoS flaw. It could occur while doing pivot_root(2) call to change root file system.

A privileged user/process could use this flaw to potentially render a system unusable leading to DoS.
