There is no update for firmware, so I do not know what to do to fix this. Message 1 of 4. Labels: Security Troubleshooting. Me too. Re: DnsMasq heap buffer overflow vulnerability. Let us know how it goes. Message 2 of 4. I will call and I will post results. Message 3 of 4. This too: Report Vulnerabilities Just another user. Message 4 of 4. At Zyxel we treat security as a top priority and we have conducted a thorough investigation and identified a list of vulnerable products within their warranty and support period, as shown in table 2 below.
For products not listed, they are not affected because they do not make use of dnsmasq. We are now deploying or backporting the latest version of dnsmasq version 2. Please refer to table 2 for the detailed release schedule. The patch firmware will be available for download at Zyxel Support Center.
