The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2366-1 advisory.
Daniel P. Berrange and Richard Jones discovered that libvirt incorrectly handled XML documents containing XML external entity declarations. An attacker could use this issue to cause libvirtd to crash, resulting in a denial of service on all affected releases, or possibly read arbitrary files if fine grained access control was enabled on Ubuntu 14.04 LTS. (CVE-2014-0179, CVE-2014-5177)
Luyao Huang discovered that libvirt incorrectly handled certain blkiotune queries. An attacker could use this issue to cause libvirtd to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3633)
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.
