Date: November 23, 2006
Bugs: #155078
ID: 200611-17

Synopsis
========
A flaw in fvwm-menu-directory may permit a local attacker to execute
arbitrary commands with the privileges of another user.
Background
==========
fvwm is a highly configurable virtual window manager for X11 desktops.
fvwm-menu-directory allows fvwm users to browse directories from within
fvwm.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-wm/fvwm < 2.5.18-r1 >= 2.5.18-r1
Description
===========
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered that
fvwm-menu-directory does not sufficiently sanitise directory names
prior to generating menus.
Impact
======
A local attacker who can convince an fvwm-menu-directory user to browse
a directory they control could cause fvwm commands to be executed with
the privileges of the fvwm user. Fvwm commands can be used to execute
arbitrary shell commands.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All fvwm users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-wm/fvwm-2.5.18-r1"
