Buffer overflow in Eudora for Windows 5.2.1, 6.0.3, and 6.1 allows remote attackers to execute arbitrary code via an e-mail with (1) a link to a long URL to the C drive or (2) a long attachment name.

Eudora 6.2.0.14 does not issue a warning when a user forwards an e-mail message that contains base64 or quoted-printable encoded attachments, which makes it easier for remote attackers to read arbitrary files via spoofed "Converted" headers.

Eudora 6.1 and 6.0.3 for Windows allows remote attackers to cause a denial of service (crash) via a deeply nested multipart MIME message.
