Authorization Bypass

virt-v2v is vulnerable to authorization bypass. The vulnerability exists as using virt-v2v to convert a guest that has a password-protected VNC console to a KVM guest removed that password protection from the converted guest: after conversion, a password was not required to access the converted guest’s VNC console. Now, converted guests will require the same VNC console password as the original guest. Note that when converting a guest to run on Red Hat Enterprise Virtualization, virt-v2v will display a warning that VNC passwords are not supported.
