DnsMasq heap buffer overflow vulnerability for Cisco voice and data modem DPC3941T

 

    Avast anti virus told me that my voice and data modem, Cisco DPC3941T, has a vunerability. DnsMasq heap buffer overflow vunerability. The fix is Version2.78, Catalogue ID  CVE-2017-14491. Does anyone else know this and what did you do? Thank you for your answer.

I got the same result.  Called tech support and they said this is a generic message that's not applicable to their devices, since they don't do anything with DNS on their devices.  Ie, according to the person I spoke with, this is not an actual vulnerability on this particular router.  I think that's likely correct, as when I login to the router, I can't find anywhere where there's any kind of DNS setting.  Hope that puts you at ease a bit.  :-)
