Description
Here are some bad RRs with invalid (empty) target (please note the space before the ;)
bad.example.org. CNAME ; bad cname
bad.example.org. HTTPS 10 ; bad https
bad.example.org. MX 10 ; bad mx
bad.example.org. SRV 1 0 80 ; bad srvThis will be parsed to the following result without error, which treat the empty blank as the \010..
bad.example.org. CNAME \010.
bad.example.org. HTTPS 10 \010.
bad.example.org. MX 10 \010.
bad.example.org. SRV 1 0 80 \010. However, if we trim the space before the ;
bad.example.org. CNAME; bad cname
bad.example.org. HTTPS 10; bad https
bad.example.org. MX 10; bad mx
bad.example.org. SRV 1 0 80; bad srvThe parser will trigger the following errors as exptected
dns: not a TTL: "CNAME" at line: 1:23
dns: bad SVCB Target: " " at line: 1:23
dns: bad MX Mx: " " at line: 1:20
dns: bad SRV Target: " " at line: 1:21
I propose to trigger error for any case that contains empty target.
