Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-3189-1 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.

Mikulas Patocka discovered that the asynchronous multibuffer
cryptographic daemon (mcryptd) in the Linux kernel did not properly
handle being invoked with incompatible algorithms. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2016-10147)

Qidan He discovered that the ICMP implementation in the Linux kernel
did not properly check the size of an ICMP header. A local attacker
with CAP_NET_ADMIN could use this to expose sensitive information.
(CVE-2016-8399).

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.
