More information:

It was discovered that there were two vulnerabilities in libvirt, an abstraction API for various virtualisation mechanisms:< />

  • CVE-2019-10161

    Readonly clients could use the API to specify an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause a denial of service or otherwise cause libvirtd to execute arbitrary programs.

  • CVE-2019-10167

    An arbitrary code execution vulnerability via the API where a user-specified binary used 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.

For Debian 8 Jessie, these problems have been fixed in version 1.2.9-9+deb8u7.

We recommend that you upgrade your libvirt packages.
