The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host’s resources and performing administrative tasks.
The following packages have been upgraded to a later upstream version: redhat-release-virtualization-host (4.3.4), redhat-virtualization-host (4.3.4). (BZ#1721058, BZ#1721062, BZ#1721065)
Security Fix(es):
kernel: tcp: integer ovrtflow while processing SACK blocks allows remote denial of service (CVE-2019-11477)
libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API (CVE-2019-10161)
libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients (CVE-2019-10166)
libvirt: arbitrary command execution via virConnectGetDomainCapabilities API (CVE-2019-10167)
libvirt: arbitrary command execution via virConnectBaselineHypervisorCPU and virConnectCompareHypervisorCPU APIs (CVE-2019-10168)
Kernel: tcp: excessive resource consumption while processing SACK blocks allows remote denial of service (CVE-2019-11478)
kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service (CVE-2019-11479)
