Descriptions
The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.
La función tipc_msg_build en net/tipc/msg.c en el kernel Linux hasta la versión 4.8.11 no valida la relación entre la longitud mínima de fragmento y el tamaño máximo de paquete, lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) aprovechando la capacidad CAP_NET_ADMIN.
