CVE-2019-10167 | BDVDB-2026-120441 Detail

libvirtlibvirt

Description#

The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" 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.

Impact#

Per CVSS v3.0: confidentiality impact high, integrity impact high, availability impact high. Attack vector: local.
