"According to the versions of the libvirt packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - It was discovered that libvirtd would permit read-only
    clients to use the virDomainSaveImageGetXMLDesc() API,
    specifying 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
    denial of service or cause libvirtd to execute
    arbitrary programs. (CVE-2019-10161)

  - The virConnectGetDomainCapabilities() libvirt API
    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. (CVE-2019-10167)

  - 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.
    (CVE-2019-10168)
