Descriptions

Stack-based buffer overflow in "dnsproxy.c" in connman 1.34 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted response query string passed to the "name" variable.

Un desbordamiento de búfer basado en pila en "dnsproxy.c" en connman 1.34 y anteriores permite que atacantes remotos provoquen una denegación de servicio (bloqueo) o ejecuten código arbitrario mediante una cadena de consulta de respuesta manipulada pasada a la variable "name".

Security consultants in NRI Secure Technologies discovered a stack overflow vulnerability in ConnMan, a network manager for embedded devices. An attacker with control of the DNS responses to the DNS proxy in ConnMan might crash the service and, in same cases, remotely execute arbitrary commands in the host running the service.
