               Fedora Legacy Update Advisory

Synopsis:          GNOME VFS updates address extfs vulnerability
Advisory ID:       FLSA:1944
Issue date:        2005-02-20
Product:           Red Hat Linux
Keywords:          Security
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1944
CVE Names:         CAN-2004-0494
-----------------------------------------------------------------------


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

Updated GNOME VFS packages that remove potential extfs-related
vulnerabilities are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

GNOME VFS is the GNOME virtual file system. It provides a modular
architecture and ships with several modules that implement support for
file systems, HTTP, FTP, and others. The extfs backends make it possible
to implement file systems for GNOME VFS using scripts.

Flaws have been found in several of the GNOME VFS extfs backend scripts.
Red Hat Linux ships with vulnerable scripts, but they are not used by
default. An attacker who is able to influence a user to open a
specially-crafted URI using gnome-vfs could perform actions as that
user. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0494 to this issue.

Users of Red Hat Linux should upgrade to these updated packages, which
remove these unused scripts.

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.

These packages are GPG signed by Fedora Legacy for security.  Our key is
available from http://www.fedoralegacy org/about/security.php

You can verify each package with the following command:

    rpm --checksig -v <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the sha1sum with the following command:

    sha1sum <filename>
