Descriptions

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.

Se encontró un fallo de falta de autorización en la API libvirt responsable de cambiar el tiempo de espera de respuesta del agente QEMU. Este fallo permite a unas conexiones de solo lectura ajustar el tiempo que libvirt espera a que el agente invitado de QEMU responder a los comandos del agente. Dependiendo del valor de tiempo de espera que es ajustado, este fallo puede hacer a unos comandos del agente invitado cometer un fallo porque el agente no puede responder a tiempo. Usuarios no privilegiados con una conexión de solo lectura podrían abusar de este fallo para ajustar el tiempo de espera de respuesta para todos los mensajes de agentes invitados en cero,potencialmente conllevando a una denegación de servicio. Este fallo afecta a versiones de libvirt anteriores a 6.2.0
