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 :

USN-3146-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

It was discovered that the __get_user_asm_ex implementation in the
Linux kernel for x86/x86_64 contained extended asm statements that
were incompatible with the exception table. A local attacker could use
this to gain administrative privileges. (CVE-2016-9644)

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)

Daxing Guo discovered a stack-based buffer overflow in the Broadcom
IEEE802.11n FullMAC driver in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash) or possibly gain
privileges. (CVE-2016-8658).

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.

Risk factor :

High / CVSS Base Score : 9.3
