Descriptions
In FreeBSD 12.2-STABLE before r365730, 11.4-STABLE before r365738, 12.1-RELEASE before p10, 11.4-RELEASE before p4, and 11.3-RELEASE before p14, a programming error in the ure(4) device driver caused some Realtek USB Ethernet interfaces to incorrectly report packets with more than 2048 bytes in a single USB transfer as having a length of only 2048 bytes. An adversary can exploit this to cause the driver to misinterpret part of the payload of a large packet as a separate packet, and thereby inject packets across security boundaries such as VLANs.
En FreeBSD versiones 12.2-STABLE anteriores a r365730, 11.4-STABLE anteriores a r365738, 12.1-RELEASE anteriores a p10, 11.4-RELEASE anteriores a p4 y 11.3-RELEASE anteriores a p14, un error de programación en el controlador de dispositivo ure(4) causó que algunas interfaces Realtek USB Ethernet reportaran incorrectamente paquetes con más de 2048 bytes en una sola transferencia USB con una longitud de solo 2048 bytes. Un adversario puede explotar esto para causar que el controlador interprete inapropiadamente parte de la carga útil de un paquete grande como un paquete separado y, por lo tanto, inyectar paquetes a través de los límites de seguridad, como las VLAN.
