Details
Ken Johnson and Jann Horn independently discovered that microprocessors
utilizing speculative execution of a memory read may allow unauthorized
memory reads via sidechannel attacks. An attacker in the guest could use
this to expose sensitive guest information, including kernel memory. This
update allows libvirt to expose new CPU features added by microcode updates
to guests. (CVE-2018-3639)
Daniel P. Berrange discovered that libvirt incorrectly handled the QEMU
guest agent. An attacker could possibly use this issue to consume
resources, leading to a denial of service. (CVE-2018-1064)
