A malicious USB device can trigger disclosure of unrelated kernel memory to userspace applications on the host, or can cause the kernel to crash. Kernel memory disclosure is especially likely on 32-bit kernels; 64-bit kernels are more likely to crash on attempted exploitation. It is not believed that kernel memory corruption is possible, or that unattended kernel memory disclosure without the collaboration of a userspace program running on the host is possible. The vulnerability is in `HoRNDIS::receivePacket`. `msg_len`, `data_ofs`, and `data_len` can be controlled by an attached USB device, and a negative value of `data_ofs` can bypass the check for `(data_ofs + data_len + 8) > msg_len`, and subsequently can cause a wild pointer copy in the `mbuf_copyback` call. The software is not maintained and no patches are planned. Users of multi-tenant systems with HoRNDIS installed should only connect trusted USB devices to their system."},{"lang":"es","value":"Todas las versiones de HoRNDIS están afectadas por un desbordamiento de enteros en las rutinas de análisis de paquetes RNDIS. Un dispositivo USB malicioso puede desencadenar la divulgación de la memoria del kernel no relacionada a las aplicaciones del espacio de usuario en el host o puede causar que el kernel se bloquee. Una divulgación de la memoria del kernel es especialmente probable en kernels de 32 bits; Es más probable que los kernels de 64 bits se bloqueen en un intento de explotación. No se cree que una corrupción de la memoria del kernel sea posible, o que una divulgación desatendida de la memoria del kernel sea posible sin la colaboración de un programa de espacio de usuario que se ejecuta en el host. La vulnerabilidad está en \"HoRNDIS::receivePacket\". \"msg_len\", \"data_ofs\" y \"data_len\" pueden ser controlados por un dispositivo USB adjunto, y un valor negativo de \"data_ofs\" puede omitir la comprobación de \"(data_ofs + data_len + 8) ) msg_len\", y posteriormente puede causar una copia de puntero wild en la llamada de \"mbuf_copyback\". El software no es mantenido y no se planean parches.
