Matthew Booth virt-v2v any version

libguestfs before 1.5.23, as used in virt-v2v, virt-inspector 1.5.3 and earlier, and possibly other products, when a raw-format disk image is used, allows local guest OS administrators to read files from the host via a crafted (1) qcow2, (2) VMDK, or (3) VDI header, related to lack of support for a disk format specifier.

virt-v2v before 0.8.4 does not preserve the VNC console password when converting a guest, which allows local users to bypass the intended VNC authentication by connecting without a password.
