ID:4059 - Exploit for Permissions, Privileges, and Access Controls in Linux kernel - CVE-2014-5207

Vulnerability description

The vulnerability allows a local #AU# to execute arbitrary code.

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.
