tag_summary = "Eggdrop Server Module is prone to a remote buffer-overflow
  vulnerability because the application fails to bounds-check
  user-supplied data before copying it into an insufficiently sized
  buffer.

  An attacker can exploit this issue to execute arbitrary code within
  the context of the affected application. Failed exploit attempts
  will result in a denial-of-service condition.

  Eggdrop 1.6.18 is known to be vulnerable; other versions may be
  affected as well.";

tag_solution = "The vendor has released an update. Please see
  http://www.eggheads.org/ for more information.";
