               Fedora Legacy Update Advisory

Synopsis:          Updated gftp package fixes security issue
Advisory ID:       FLSA:152908
Issue date:        2005-07-10
Product:           Red Hat Linux, Fedora Core
Keywords:          Bugfix
CVE Names:         CAN-2005-0372
- ---------------------------------------------------------------------


- ---------------------------------------------------------------------
1. Topic:

Updated gftp packages that fix a security issue are now available.

gFTP is a multi-threaded FTP client for the X Window System.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

A directory traversal vulnerability was discovered in gftp. A remote
malicious FTP server could read, overwrite or create arbitrary files
via .. (dot dot) sequences in the filenames returned from a LIST
command. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0372 to this issue.

Users of gftp are advised to upgrade to these errata packages, which
contain a backported patch correcting this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which
are not installed but included in the list will not be updated.  Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt.  Many
people find this an easier way to apply updates.  To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.  This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
