Vulnerability from csaf_redhat - Published: 2022-11-15 13:21 - Updated: 2025-11-21 18:34Summary
Red Hat Security Advisory: virt-v2v security, bug fix, and enhancement update
Severity
Low
Notes
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.
Details: 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)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.1 Release Notes linked from the References section.
