Synopsis
========

A vulnerability in Smb4K could allow local attackers to execute
commands as root.

Background
==========

Smb4K is a SMB/CIFS (Windows) share browser for KDE.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/smb4k             < 1.2.3-r1               >= 1.2.3-r1 

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

Smb4k contains a logic flaw in which mount helper binary does not
properly verify the mount command it is being asked to run.

Impact
======

A local user can execute commands with the root privilege due to the
mount helper being installed as suid.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Smb4K users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/smb4k-1.2.3-r1:4 "
