Analysis of Questionable CVEs Reported Against dnsmasq Configuration Vulnerabilities
By

A good honest bake. Not flashy, but you'll finish the whole bagel.
Summary
The article discusses questionable CVEs (Common Vulnerabilities and Exposures) reported against dnsmasq, a DNS server software. The author points out that the reported vulnerabilities require an attacker to replace the default configuration file (/etc/dnsmasq.conf) with a malicious file. The argument is that if an attacker already has the ability to replace the server's configuration file, they don't need to exploit parser vulnerabilities but can simply change the configuration directly, making the reported CVEs questionable in their practical security impact.

For all three bugs, the documented 'exploit' requires 'Replace the default configuration file (/etc/dnsmasq.conf) with the provided malicious file.'
if you can replace the server's configuration file you don't need to play games with putting invalid contents in to break the parser, but can simply change the configuration
