Synopsis
=======
Under certain conditions, applications linked against uim suffer from a
privilege escalation vulnerability.

Background
=========
uim is a simple, secure and flexible input method library.

Affected packages
================
    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  app-i18n/uim      < 0.4.5.1                            >= 0.4.5.1

Description
==========
Takumi Asaki discovered that uim insufficiently checks environment
variables. setuid/setgid applications linked against libuim could end
up executing arbitrary code. This vulnerability only affects
immodule-enabled Qt (if you build Qt 3.3.2 or later versions with
USE="immqt" or USE="immqt-bc").

Impact
=====
A malicious local user could exploit this vulnerability to execute
arbitrary code with escalated privileges.

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

Resolution
=========
All uim users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-i18n/uim-0.4.5.1"
