This is a glibc issue, not a bind issue.  It makes no sense to attempt
to fix the problem by modifying bind.  Firstly, bind is not the only
software which may call glibc's getaddrinfo() function in a way which
could permit exploitation, and secondly, a 'sticking plaster' fix is
likely to come unstuck anyway.

I fear that there's no alternative.
