DESCRIPTION:
A weakness has been reported in NetBSD, which can be exploited by
malicious users to cause a DoS (Denial of Service).

The weakness is caused due to an insufficient GLOB_LIMIT
implementation, which can be exploited to exhaust memory or cause a
high CPU load via specially crafted patterns in commands passed to
e.g. the ftpd or sftp server processes.

SOLUTION:
Fixed in the CVS repository.
