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 :

USN-2746-1 fixed a vulnerability in Simple Streams. The update caused
a regression preventing MAAS from downloading PXE images. This update
fixes the problem.

We apologize for the inconvenience.

It was discovered that Simple Streams did not properly perform gpg
verification in some situations. A remote attacker could use this to
perform a man-in-the-middle attack and inject malicious content into
the stream.

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.
