A memory allocation bug in Freeciv allows a remote attacker to perform a
Denial of Service attack.
Freeciv is an open source turn-based multiplayer strategy game,
similar to the famous Civilization series.
Luigi Auriemma discovered that Freeciv could be tricked into the
allocation of enormous chunks of memory when trying to uncompress
malformed data packages, possibly leading to an out of memory condition
which causes Freeciv to crash or freeze.
A remote attacker could exploit this issue to cause a Denial of
Service by sending specially crafted data packages to the Freeciv game
