MaraDNS CVE-2011-0520 vulnerability can not allow remote code execution

[Sam Trenholme]

The following three websites claim that the vulnerability
CVE-2011-0520 allows remote code execution:

http://www.securityfocus.com/bid/45966/info

http://xforce.iss.net/xforce/xfdb/64885

http://secunia.com/advisories/43027

This is not true.  The data placed on the overflowed buffer are not
controlled by a potential attacker; they are merely a series of
increasing integers which will not contain executable code.

Also, I have patched this bug and have released both MaraDNS 1.4.06
and MaraDNS 1.3.07.11 with this patch.
