🚨 A long "MAIL FROM" or "RCPT TO" command is all it takes for an attacker to exploit this buffer overflow in All-Mail 1.1! Think of it as sending a parcel with an address so long it spills over the label, confusing the postal service and allowing someone to sneak in and replace the contents with anything they want! This vulnerability lets attackers execute arbitrary commands on the server, potentially giving them full control. It’s a bit like letting a stranger into your home because you forgot to check the package they’re delivering — absolutely devastating!
