    Synopsis
    ========

    Weex contains a format string error that may be exploited by malicious
    servers to execute arbitrary code.

    Background
    ==========

    Weex is a non-interactive FTP client typically used to update web
    pages.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-ftp/weex < 2.6.1.5-r1 >= 2.6.1.5-r1

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

    Ulf Harnhammar discovered a format string bug in Weex that can be
    triggered when it is first run (or when its cache files are rebuilt,
    using the -r option).

    Impact
    ======

    An attacker could setup a malicious FTP server which, when accessed
    using Weex, could trigger the format string bug and end up executing
    arbitrary code with the rights of the user running Weex.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Weex users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-ftp/weex-2.6.1.5-r1"
