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)

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).
