Avast Pro Anti-Virus reports that my HiTron CGNM-2250 modem/router DNS Service has a severe "DnsMasq heap buffer overflow vulnerability". (Who knew!?) This is accompanied by practical threats too awesome to even contemplate - hijackings and malformations and OMG execution of arbitrary code!!! Bad enough that this affects the puter wifi but reportedly these horrors can extend to phones, tablets, printers, security cameras and anything else connected to the network. I don't even think my fridge is safe.
Anyway, apparently, the issue was fixed in DnsMasq software version 2.78 released in October 2017.
How do we get hold of this before doom strikes?
