Synopsis
========

Two buffer overflow vulnerabilities have been discovered in fsplib code
used in gFTP.

Background
==========

gFTP is an FTP client for the GNOME desktop environment.

Affected packages
=================

    -------------------------------------------------------------------
     Package       /   Vulnerable   /                       Unaffected
    -------------------------------------------------------------------
  1  net-ftp/gftp      < 2.0.18-r6                        >= 2.0.18-r6

Description
===========

Kalle Olavi Niemitalo discovered two boundary errors in fsplib code
included in gFTP when processing overly long directory or file names.

Impact
======

A remote attacker could trigger these vulnerabilities by enticing a
user to download a file with a specially crafted directory or file
name, possibly resulting in the execution of arbitrary code
(CVE-2007-3962) or a Denial of Service (CVE-2007-3961).

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All gFTP users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/gftp-2.0.18-r6"
