Descriptions

Heap-based buffer overflow in the tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, might allow remote attackers to execute arbitrary code via a long filename in a TFTP packet, as demonstrated by a read (aka RRQ) request.

Desbordamiento de búfer basado en memoria dinámica en la función tftp_request en tftp.c en dnsmasq anterior v2.50, cuando --enable-tftp es usado, puede permitir a atacantes remotos ejecutar código a su elección a través de un nombre de fichero largo en un paquete TFTP, como queda demostrado en una lectura de respuesta (RRQ).
