Stack overflow when parsing malicious DNS packet

There's a stack overflow leading to a crash when Trust-DNS's parses a malicious DNS packet. Affected versions of this crate did not properly handle parsing of DNS message compression RFC1035 section 4.1.4. The parser could be tricked into infinite loop when a compression offset pointed back to th...

DNS Server on UDP and TCP

A DNS server is running on this port but it only answers to UDP requests. This means that TCP requests are blocked by a firewall. This configuration is incorrect: TCP might be used by any request, it is not restricted to zone transfers. Read RFC1035 or STD0013 for more information. This VT has be...
