TITLE:
FreeBSD ftpd chroot Security Bypass Security Issue

SECUNIA ADVISORY ID:
SA36353

VERIFY ADVISORY:
http://secunia.com/advisories/36353/

DESCRIPTION:
Kingcope has discovered a security issue in FreeBSD's ftpd, which can
be exploited by malicious users to bypass certain security
restrictions.

The security issue is caused due to the ftpd not correctly checking
for certain error conditions when trying to read a user's chroot
information from /etc/ftpchroot. A user can exploit this to bypass
the chroot protection by e.g. uploading ".login_conf" and
".login_conf.db" files with the "openfiles" resource limit set to 5
into a home directory.

The security issue is confirmed in FreeBSD 7.2. Other versions may
also be affected.

SOLUTION:
Allow access to trusted users only. Do not rely on the chroot
protection.

PROVIDED AND/OR DISCOVERED BY:
Kingcope
