A cross-site scripting vulnerability was reported in ovirt-engine's OAuth authorization endpoint. URL parameters would be included in the HTML response without escaping, allowing an attacker to craft malicious HTML pages that could run scripts in the context of the user's ovirt session.

Remedy

The Unix permissions of libvirt's read-only socket can be made more restrictive than the default (0777) by editing `/etc/libvirt/libvirtd.conf`. The settings `unix_sock_group = libvirt` and `unix_sock_ro_perms = 0770` will restrict access to only members of `libvirt`, who already have management access to virtual machines.

It was discovered that libvirtd would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed.

This vulnerability was first present in libvirt v3.6.1.
