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 :

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)

It was discovered that a use-after-free existed in the KVM susbsystem
of the Linux kernel when creating devices. A local attacker could use
this to cause a denial of service (system crash). (CVE-2016-10150)

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)

Qian Zhang discovered a heap-based buffer overflow in the
tipc_msg_build() function in the Linux kernel. A local attacker could
use to cause a denial of service (system crash) or possible execute
arbitrary code with administrative privileges. (CVE-2016-8632)

Dmitry Vyukov discovered that the KVM implementation in the Linux
kernel did not properly restrict the VCPU index when I/O APIC is
enabled, An attacker in a guest VM could use this to cause a denial of
service (system crash) or possibly gain privileges in the host OS.
(CVE-2016-9777).

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.
