This is just a bug, it's not a security issue. And don't send binary
attachments, nobody sane would open a binary attachment sent on a
mailing list.
If you want to get credit for finding a fixing a bug, just send a
patch for it. That's what I told you to do, not send the same "report"
style on the public list. A patch is something that can get reviewed and
applied.
