Description

An update for libguestfs and virt-p2v is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security 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:
libguestfs (1.32.7), virt-p2v (1.32.7). (BZ#1218766)

(CVE-2015-8869)

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