Oracle Linux 8 : virt-manager (ELSA-2019-3464)

The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2019-3464 advisory.

  • Virt-install(1) utility used to provision new virtual machines has introduced an option β€˜β€“unattended’ to create VMs without user interaction. This option accepts guest VM password as command line arguments, thus leaking them to others users on the system via process listing. It was introduced recently in the virt- manager v2.2.0 release. (CVE-2019-10183)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
