COMMAND
ncftp
SYSTEMS AFFECTED
Ncftpd prior to 2.6.2
PROBLEM
Thiago Madeira de Lima found following. Found this bug 2 weeks
ago and reported to the author. Now there's a new version that
solves the problem. This bug only works if you use the same UID
or GID for more than 1 user.
Restricted users could access directory paths that were prefixed
by the entire pathname of the home directory and if the user's
UID/GID privileges allowed it.
For example, a user bill with home directory /home/users/bill may
have been able to access the directory /home/users/billybob if
bill's privileges allowed it.
SOLUTION
Everyone using ncftpd prior 2.6.2 should upgrade to ncftpd 2.6.2.
