    Multiple buffer overflows have been reported in OpenTTD, when storing
    long for client names (CVE-2008-3547), in the TruncateString function
    in src/gfx.cpp (CVE-2008-3576) and in src/openttd.cpp when processing a
    large filename supplied to the '-g' parameter in the ttd_main function
    (CVE-2008-3577).
  
Impact :

    An authenticated attacker could exploit these vulnerabilities to
    execute arbitrary code with the privileges of the OpenTTD server.
  
Workaround :

    There is no known workaround at this time."
