Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: libvirt (affected versions not specified)

Description: The issue is related to the util/virlog.c in libvirt, which does not properly determine the hostname on LXC container startup. This allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module. The exploitation of this issue may allow an attacker to access confidential data, compromise their integrity, and cause a denial of service.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
