    Cube is an open source first person shooter game engine supporting
    multiplayer via LAN or internet.

    <p>
    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).
    </p>
  </description>
  <impact type="high">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    Play solo games or restrict your multiplayer games to trusted
    parties.
    </p>
  </workaround>
  <resolution>
    <p>
    Upstream stated that there will be no fixed version of Cube, thus
    the Gentoo Security Team decided to hardmask Cube for security reasons.
    All Cube users are encouraged to uninstall Cube:
    </p>
    <code>
    # emerge --ask --unmerge games-fps/cube</code>
  </resolution>
