Summary

Eudora 5.1 allows remote attackers to execute arbitrary code when the "Use Microsoft Viewer" option is enabled and the "allow executables in HTML content" option is disabled, via an HTML email with a form that is activated from an image that the attacker spoofs as a link, which causes the user to execute the form and access embedded attachments.
