    Synopsis
    ========

    An overflow in the camel-lock-helper application can be exploited by an
    attacker to execute arbitrary code with elevated privileges.

    Background
    ==========

    Evolution is a GNOME groupware application similar to Microsoft
    Outlook.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 mail-client/evolution <= 2.0.2 >= 2.0.2-r1

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

    Max Vozeler discovered an integer overflow in the camel-lock-helper
    application, which is installed as setgid mail by default.

    Impact
    ======

    A local attacker could exploit this vulnerability to execute malicious
    code with the privileges of the 'mail' group. A remote attacker could
    also setup a malicious POP server to execute arbitrary code when an
    Evolution user connects to it.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Evolution users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose
        # ">=mail-client/evolution-2.0.2-r1"
