Descriptions

qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.

qemu-bridge-helper.c en QEMU versión 3.1 y 4.0.0 no garantiza que un nombre de interfaz de red (obtenido de bridge.conf o una opción --br = bridge) esté limitado al tamaño de IFNAMSIZ, lo que puede llevar a una derivación de ACL.
