Descriptions

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.

La API libvirt de la función virConnectGetDomainCapabilities(), versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, acepta un argumento "emulatorbin" para especificar el programa que proporciona emulación para un dominio. Desde versión v1.2.19, libvirt ejecutará ese programa para examinar las capacidades del dominio. Los clientes de solo lectura podrían especificar una ruta de acceso arbitraria para este argumento, causando que libvirtd activara un ejecutable diseñado con sus propios privilegios.
