Synopsis
=======
SUS contains a string format bug that could lead to local privilege
escalation.

Background
=========
SUS is a utility that allows regular users to be able to execute
certain commands as root.

Affected packages
================
    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  app-admin/sus     < 2.0.2-r1                          >= 2.0.2-r1

Description
==========
Leon Juranic found a bug in the logging functionality of SUS that can
lead to local privilege escalation. A format string vulnerability
exists in the log() function due to an incorrect call to the syslog()
function.

Impact
=====
An attacker with local user privileges can potentially exploit this
vulnerability to gain root access.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All SUS users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=app-admin/sus-2.0.2-r1"
    # emerge ">=app-admin/sus-2.0.2-r1"
