RedHat: RHSA-2022-7968:01 Low: virt-v2v security, bug fix,
Summary
The virt-v2v package provides a tool for converting virtual machines to use
the KVM (Kernel-based Virtual Machine) hypervisor or Red Hat Enterprise
Virtualization. The tool modifies both the virtual machine image and its
associated libvirt metadata. Also, virt-v2v can configure a guest to use
VirtIO drivers if possible.
Security Fix(es):
* libguestfs: Buffer overflow in get_keys leads to DoS (CVE-2022-2211)
