Ubuntu 14.04 LTS / 14.10 : libvirt vulnerabilities (USN-2404-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Pavel Hrdina discovered that libvirt incorrectly handled locking when
processing the virConnectListAllDomains command. An attacker could use
this issue to cause libvirtd to hang, resulting in a denial of
service. (CVE-2014-3657)

Eric Blake discovered that libvirt incorrectly handled permissions
when processing the qemuDomainFormatXML command. An attacker with
read-only privileges could possibly use this to gain access to certain
information from the domain xml file. (CVE-2014-7823).

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 libvirt-bin and / or libvirt0 packages.
