CVE-2019-10168

Public on 2019-08-02
Modified on 2019-08-27
Description

The virConnectBaselineHypervisorCPU() and virConnectCompareHypervisorCPU() libvirt APIs accept an "emulator" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.
