Published: Translated: NVD NIST

Summary

Buffer overflow vulnerability in Freeciv 2.1.0-beta1 and earlier, and SVN 15 Jul 2006 and earlier. A remote attacker can cause a denial of service (crash) and possibly execute arbitrary code by manipulating packet values such as a negative chunk_length, a large chunk->offset, or a large packet->length.

Risk Assessment

An organization using an affected version of Freeciv may experience a game server crash or, in the worst case, remote code execution by an attacker, potentially leading to system compromise.

Recommendation

Update Freeciv to the latest version that does not contain this vulnerability. If updating is not possible, consider restricting access to the game server to trusted users only.
