    Synopsis
    ========

    Under certain conditions, applications linked against Uim suffer from a
    privilege escalation vulnerability.

    Background
    ==========

    Uim is a multilingual input method library which provides secure and
    useful input method for all languages.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 app-i18n/uim < 0.4.9.1 >= 0.4.9.1

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

    Masanari Yamamoto discovered that Uim uses environment variables
    incorrectly. This bug causes a privilege escalation if setuid/setgid
    applications are linked to libuim. This bug 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 version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=app-i18n/uim-0.4.9.1"

    References
    ==========
