FKIE_CVE-2020-15137

Vulnerability from fkie_nvd - Published: 2020-08-12 17:15 - Updated: 2024-11-21 05:04
Severity
5.5 (Medium) - CVSS:3.1/AV:P/AC:H/PR:L/UI:R/S:U/C:H/I:N/A:H
5.9 (Medium) - CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
All versions of HoRNDIS are affected by an integer overflow in the RNDIS packet parsing routines. 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.

      "value": "Todas las versiones de HoRNDIS est\u00e1n afectadas por un desbordamiento de enteros en las rutinas de an\u00e1lisis de paquetes RNDIS. Un dispositivo USB malicioso puede desencadenar la divulgaci\u00f3n 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 divulgaci\u00f3n de la memoria del kernel es especialmente probable en kernels de 32 bits; Es m\u00e1s probable que los kernels de 64 bits se bloqueen en un intento de explotaci\u00f3n. No se cree que una corrupci\u00f3n de la memoria del kernel sea posible, o que una divulgaci\u00f3n desatendida de la memoria del kernel sea posible sin la colaboraci\u00f3n de un programa de espacio de usuario que se ejecuta en el host. La vulnerabilidad est\u00e1 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 comprobaci\u00f3n 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. Los usuarios de sistemas multi-tenant con HoRNDIS instalado solo deben conectar dispositivos USB confiables a su sistema"
