Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that virtio networking in the Linux kernel did not
handle fragments correctly, leading to kernel memory corruption. A
remote attacker could use this to cause a denial of service (system
crash) or possibly execute code with administrative privileges.
(CVE-2015-5156)

It was discovered that the Reliable Datagram Sockets (RDS)
implementation in the Linux kernel did not verify sockets were
properly bound before attempting to send a message, which could cause
a NULL pointer dereference. An attacker could use this to cause a
denial of service (system crash). (CVE-2015-6937).

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.
