A missing authorization flaw was found in the libvirt API responsible for
changing the QEMU agent response timeout. This flaw allows read-only
connections to adjust the time that libvirt waits for the QEMU guest agent
to respond to agent commands. Depending on the timeout value that is set,
this flaw can make guest agent commands fail because the agent cannot
respond in time. Unprivileged users with a read-only connection could abuse
this flaw to set the response timeout for all guest agent messages to zero,
potentially leading to a denial of service. This flaw affects libvirt
versions before 6.2.0.
