(Cube: Multiple vulnerabilities)

    Luigi Auriemma reported that Cube is vulnerable to a buffer
    overflow in the sgetstr() function (CVE-2006-1100) and that the
    sgetstr() and getint() functions fail to verify the length of the
    supplied argument, possibly leading to the access of invalid memory
    regions (CVE-2006-1101). Furthermore, he discovered that a client
    crashes when asked to load specially crafted mapnames (CVE-2006-1102).
  
Impact :

    A remote attacker could exploit the buffer overflow to execute
    arbitrary code with the rights of the user running cube. An attacker
    could also exploit the other vulnerabilities to crash a Cube client or
    server, resulting in a Denial of Service.
  
Workaround :

    Play solo games or restrict your multiplayer games to trusted
    parties."
