|
|
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.

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could exploit this issue to cause a Denial of
|
|
Service by sending specially crafted data packages to the Freeciv game
|
|
server.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Play solo games or restrict your multiplayer games to trusted
|
|
parties.
|
|
</p>
|
|
</workaround>

|
<resolution>
|
|
<p>
|
|
All Freeciv users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=games-strategy/freeciv-2.0.8"</code>
