Eudora contains a flaw that may allow a malicious user to bypass the user warning for executable attachments, such as .exe, .com, and .bat files. The issue is triggered by using an attached .lnk file that refers to the executable, or "Stealth Attachment." It is possible that the flaw may allow arbitrary code to be executed by an attacker without prompting the user.
