(Doomsday: Multiple vulnerabilities)

    Luigi Auriemma discovered multiple buffer overflows in the
    D_NetPlayerEvent() function, the Msg_Write() function and the
    NetSv_ReadCommands() function. He also discovered errors when handling
    chat messages that are not NULL-terminated (CVE-2007-4642) or contain a
    short data length, triggering an integer underflow (CVE-2007-4643).
    Furthermore a format string vulnerability was discovered in the
    Cl_GetPackets() function when processing PSV_CONSOLE_TEXT messages
    (CVE-2007-4644).
  
Impact :

    A remote attacker could exploit these vulnerabilities to execute
    arbitrary code with the rights of the user running the Doomsday server
    or cause a Denial of Service by sending specially crafted messages to
    the server.
  
Workaround :

    There is no known workaround at this time."
