After months of touting Vista as the answer to the prayers of users seeking a secure Windows operating system, a new critical vulnerability has arisen as a retort to Microsoft's claims. The vulnerability in Vista's email client Windows Mail would qualify for critical status, allowing a remote code execution exploit, if addressed by Microsoft under its monthly patching cycle.

According to the Kingcope: "Remote Code Execution is possible if a user clicks on a malicious prepared link. Vistas Mail Client will execute any executable file if a folder exists with the same name. For example the victim has a folder in C:\ named blah and a batch script named blah.bat also in C:\. Now if the victim clicks on a link in the email message with the URL target set to C:\blah the batch script is executed without even asking. There is for example a CMD script by default in C:\Windows\System32\ named winrm.cmd (and also a folder named winrm inside System32)." Needless to say, the description provides a perfect example as to why email recipients should not click on links from unknown sources.
