    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"
