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=E2=80=88 >= 1.2=
.3-r1=E2=80=88
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=E2=80=
=88"
