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.
