impact of Moderate. 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.

The libguestfs packages contain a library, which is used for accessing
and modifying virtual machine (VM) disk images.

Virt-p2v is a tool for conversion of a physical server to a virtual
guest.

The following packages have been upgraded to a newer upstream version:

Note: The libguestfs packages in this advisory were rebuilt with a
fixed version of OCaml to address this issue.
