now deprecated in the standards.

Simon Kelley 5d07d77e75 Fix buffer overflow introduced in 2.73rc6.
Fix off-by-one in code which checks for over-long domain names
in received DNS packets. This enables buffer overflow attacks
which can certainly crash dnsmasq and may allow for arbitrary
code execution. The problem was introduced in commit b8f16556d,
release 2.73rc6, so has not escaped into any stable release.
Note that the off-by-one was in the label length determination,
so the buffer can be overflowed by as many bytes as there are
labels in the name - ie, many.

Thanks to Ron Bowes, who used lcmatuf's afl-fuzz tool to find
the problem.

Simon Kelley fe3992f9fa Return INSECURE, rather than BOGUS when DS proved not to exist.
Return INSECURE when validating DNS replies which have RRSIGs, but
when a needed DS record in the trust chain is proved not to exist.
It's allowed for a zone to set up DNSKEY and RRSIG records first, then
add a DS later, completing the chain of trust.

Also, since we don't have the infrastructure to track that these
non-validated replies have RRSIGS, don't cache them, so we don't
provide answers with missing RRSIGS from the cache.
