DESCRIPTION:
A vulnerability has been reported in Eudora WorldMail IMAP Server,
which can be exploited by malicious users to bypass certain security
restrictions and to gain access to potentially sensitive
information.

The vulnerability is caused due to a directory traversal error in
various IMAP folder manipulation commands. This can be exploited to
read arbitrary user's emails and to move arbitrary folders on the
system by supplying folder names containing directory traversal
sequences to the affected IMAP commands (e.g. select).

Successful exploitation requires logon to the IMAP server.

The vulnerability has been reported in version 3.0. Prior versions
may also be affected.

SOLUTION:
Grant only trusted users access to the IMAP server, or disable IMAP
access.
