RHSA-2022:7968 - Security Advisory

Topic

An update for virt-v2v is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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)
