DESCRIPTION:
Ubuntu has issued an update for the kernel. This fixes multiple
vulnerabilities, which can be exploited by malicious, local users to
bypass certain security restrictions and gain escalated privileges
and by malicious people to compromise a vulnerable system and cause a
DoS (Denial of Service).

For more information:
SA47378
SA47472
SA47488

1) The vulnerability is caused due to the Overlayfs filesystem not
properly checking extended permissions, which can be exploited to
gain access to otherwise restricted files.
