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

Description:

This update for libvirt fixes the following issues:

Security issue 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 issues addressed:

• libxl: support Xen's max_grant_frames setting with maxGrantFrames attribute on the xenbus controller (bsc#1126325).
• conf: added new 'xenbus' controller type
• util: skip RDMA detection for non-PCI network devices (bsc#1112182).
• qemu: don't use CAP_DAC_OVERRIDE capability if non-root (bsc#1125665).
• qemu: fix issues related to restricted permissions on /dev/sev(bsc#1102604).
• libxl: save current memory value after successful balloon (bsc#1120813).
• libxl: Add support for soft reset. (bsc#1081516)
