Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A memory allocation bug in Freeciv allows a remote attacker to perform |
| 19 |
a Denial of Service attack. |
| 20 |
|
| 21 |
Background |

========== |
| 23 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Luigi Auriemma discovered that Freeciv could be tricked into the |
| 39 |
allocation of enormous chunks of memory when trying to uncompress |
| 40 |
malformed data packages, possibly leading to an out of memory condition |
| 41 |
which causes Freeciv to crash or freeze. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could exploit this issue to cause a Denial of Service |
| 47 |
by sending specially crafted data packages to the Freeciv game server. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
Play solo games or restrict your multiplayer games to trusted parties. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Freeciv users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=games-strategy/freeciv-2.0.8" |
| 61 |
