NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-devel package and not the libvirt-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

A flaw was found in libvirt. During storage volume clone or convert operations, newly created volume images were temporarily world-readable. This was caused by the qemu-img utility running with overly permissive file creation settings, allowing any local user to read the full guest disk contents. This vulnerability could lead to sensitive information disclosure from guest virtual machines.
