Stack-based buffer overflow in the FTP server in Etype Eserv 3.x, possibly 3.26, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a long argument to the ABOR command.

Buffer overflow in the logging feature of EServ 2.9.2 and earlier allows an attacker to execute arbitrary commands via a long MKD command.

EServ 2.92 Build 2982 allows remote attackers to cause a denial of service and possibly execute arbitrary commands via long HELO and MAIL FROM commands.

Etype Eserv 2.97 allows remote attackers to view password protected files via /./ in the URL.

Etype Eserv 2.97 allows remote attackers to cause a denial of service (resource exhaustion) via a large number of PASV commands that consume ports 1024 through 5000, which prevents the server from accepting valid PASV.

Directory traversal vulnerability in Etype Eserv 2.50 web server allows a remote attacker to read any file in the file system via a .. (dot dot) in a URL.

Memory leak in eServ 2.9x allows remote attackers to cause a denial of service (memory exhaustion) via a large number of connections, whose memory is not freed when the connection is terminated.

The (1) FTP, (2) POP3, (3) SMTP, and (4) NNTP servers in EServer 2.92 through 2.97, and possibly 2.98, allow remote attackers to cause a denial of service (crash) via a large amount of data.

Directory traversal vulnerability in the IMAP service in EServ/3 3.25 allows remote authenticated users to read other user's email messages, create/rename arbitrary directories on the system, and delete empty directories via directory traversal sequences in the (1) CREATE, (2) SELECT, (3) DELETE, (4) RENAME, (5) COPY or (6) APPEND commands.
