Ubuntu 16.10 : linux vulnerabilities (USN-3147-1)

Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Andreas Gruenbacher and Jan Kara discovered that the filesystem
implementation in the Linux kernel did not clear the setgid bit during
a setxattr call. A local attacker could use this to possibly elevate
group privileges. (CVE-2016-7097)

Marco Grassi discovered that the driver for Areca RAID Controllers in
the Linux kernel did not properly validate control messages. A local
attacker could use this to cause a denial of service (system crash) or
possibly gain privileges. (CVE-2016-7425).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.
