    Synopsis
    ========

    Open DC Hub contains a buffer overflow that can be exploited to allow
    remote code execution.

    Background
    ==========

    Open DC Hub is the hub software for the Direct Connect file sharing
    network.

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

      1 net-p2p/opendchub < 0.7.14-r2 >= 0.7.14-r2

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

    Donato Ferrante discovered a buffer overflow vulnerability in the
    RedirectAll command of the Open DC Hub.

    Impact
    ======

    Upon exploitation, a remote user with administrative privileges can
    execute arbitrary code on the system running the Open DC Hub.
