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

Medium Nessus Plugin ID 79210


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


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.


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