Descriptions
dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests.
Las versiones anteriores a la 2.78 de dnsmasq, cuando se configuran como retransmisor, permiten que los atacantes remotos obtengan información sensible de la memoria mediante vectores relacionados con la gestión de peticiones DHCPv6 reenviadas.
An information leak was found in dnsmasq in the DHCPv6 relay code. An attacker on the local network could send crafted DHCPv6 packets to dnsmasq causing it to forward the contents of process memory, potentially leaking sensitive data.
Dnsmasq versions prior to 2.78 suffer from an information leak vulnerability.
