An update that solves two vulnerabilities and has three security fixes can now be installed.

Description:

This update for libvirt fixes the following issues:

Security issues fixed:

• CVE-2019-3840: Fixed a null pointer dereference vulnerability in virJSONValueObjectHasKey function which could have resulted in a remote denial of service via the guest agent (bsc#1127458).
• CVE-2019-3886: Fixed an information leak which allowed to retrieve the guest hostname under readonly mode (bsc#1131595).

Other issue addressed:

• cpu: add Skylake-Server and Skylake-Server-IBRS CPU models (FATE#327261, bsc#1131955)
• libxl: save current memory value after successful balloon (bsc#1120813).
• libxl: support Xen's max_grant_frames setting with maxGrantFrames attribute on the xenbus controller (bsc#1126325).
• conf: add new 'xenbus' controller type
