The Netware FTP Server Contains a DoS vulnerability
The Netware FTP server has a DOS vulnerability. An attacker could cause
the server CPU to spike at 100% CPU hogging the server and causing a DOS,
preventing legitimate users access to the server.
* Novell Netware 6.0 SP 1
An attacker could cause the server to spike at 100% CPU, prohibiting
legitimate users to access the server. This is done by connecting to the
server using netcat or telnet and simply typing an enter. Due to the
impact of this issue, it is not recommended to have unprotected ftp
servers on public networks. Since there is no patch yet, we urge you to
shutdown the ftp server or filter incoming connections as soon as
Disable the ftp server or make sure only trusted people can connect to it
by filtering incoming connections.
Install patch from Novell as soon as it becomes available.
Novell was contacted 20020408 but has not yet responded to the issue.
