Eudora WorldMail is an e-mail server for Windows.
Eudora WorldMail version 9.0.333.0 (and probably earlier) IMAPd service is vulnerable to buffer overflow as a result of improper validation of user-supplied input when handling UID commands.
Contact the vendor to determine if an update is planned. The Eudora WorldMail page indicates that Qualcomm no longer sells Worldmail, but technical support is still available.
Expoit works on Eudora Qualcomm WorldMail 9.0.333.0 IMAPd Service running on Windows Server 2003 SP1.
