NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace package and not the kernel-rt-trace package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call.
