Description Prasad Pandit 2013-09-05 11:31:20 UTC
Linux kernel built with the user name-spaces is vulnerable to an incorrect
name-space check when spoofing PID in routine scm_check_creds(). This could
lead to privilege escalation to gain root access to a system.

A local user/program could use this flaw to escalate privileges to gain root
access to the system.
