Ubuntu Security Notice (C) 2014-2017 Canonical, Inc. / NASL script (C) 2014-2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

Michael S. Tsirkin, Anthony Liguori, and Michael Roth discovered
multiple issues with QEMU state loading after migration. An attacker
able to modify the state data could use these issues to cause a denial
of service, or possibly execute arbitrary code. (CVE-2013-4148,

CVE-2014-0182, CVE-2014-3461)

Kevin Wolf, Stefan Hajnoczi, Fam Zheng, Jeff Cody, Stefan Hajnoczi,
and others discovered multiple issues in the QEMU block drivers. An
attacker able to modify disk images could use these issues to cause a
denial of service, or possibly execute arbitrary code. (CVE-2014-0142,
CVE-2014-0143, CVE-2014-0144, CVE-2014-0145, CVE-2014-0146,
CVE-2014-0147, CVE-2014-0222, CVE-2014-0223)

It was discovered that QEMU incorrectly handled certain PCIe bus
hotplug operations. A malicious guest could use this issue to crash
the QEMU host, resulting in a denial of service. (CVE-2014-3471).

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.
