CVE-2014-5207

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and changing MNT_ATIME_MASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, or cause a denial of service (excessive filesystem updating) on systems that had atime disabled via a "mount -o remount" command within a user namespace.

Not vulnerable.

This issue did not affect the versions of kernel as shipped with Red Hat Enterprise Linux 5, 6, 7, and Red Hat Enterprise Linux MRG 2.
