NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allows user-assisted remote attackers to cause a denial of service (console hang) via a large number of FTP sessions, which are not properly handled during an NLM unload.
Multiple buffer overflows in NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 allow remote attackers to cause a denial of service (abend) via a long (1) username or (2) password.
NWFTPD.nlm in the FTP server in Novell NetWare 6.0 before SP4 and 6.5 before SP1 does not enforce domain-name login restrictions, which allows remote attackers to bypass intended access control via an FTP connection.
NWFTPD.nlm before 5.04.05 in the FTP server in Novell NetWare 6.5 does not properly enforce FTPREST.TXT settings, which allows remote attackers to bypass intended access restrictions via an FTP session.
NWFTPD.nlm before 5.04.05 in the FTP server in Novell NetWare 6.5 does not properly perform "intruder detection," which has unspecified impact and attack vectors.
NWFTPD.nlm before 5.03.12 in the FTP server in Novell NetWare does not properly restrict filesystem use by anonymous users with NFS Gateway home directories, which allows remote attackers to bypass intended access restrictions via an FTP session.
NWFTPD.nlm before 5.04.25 in the FTP server in Novell NetWare does not promptly close DS sessions, which allows remote attackers to cause a denial of service (connection slot exhaustion) by establishing many FTP sessions that persist for the lifetime of a DS session.
NWFTPD.nlm before 5.06.04 in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (excessive stale connections) by establishing many FTP sessions, which persist in the Not-Logged-In state after each session is completed.
NWFTPD.nlm before 5.08.07 in the FTP server in Novell NetWare 6.5 SP7 does not properly implement the FTPREST.TXT NOREMOTE restriction, which allows remote authenticated users to access directories outside of the home server via unspecified vectors.
