DESCRIPTION:
A vulnerability has been reported in Novell NetWare, which can be
exploited by malicious users to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within NWFTPD.NLM
when processing FTP commands. This can be exploited to cause a
stack-based buffer overflow via specially crafted arguments passed to
the DELE command.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in NWFTPD.NLM versions prior to
5.10.02.

SOLUTION:
Update NWFTPD.NLM to version 5.10.02.
