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

critical Nessus Plugin ID 79210

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2404-1 advisory.

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libvirt-bin, libvirt-dev and / or libvirt0 packages.
