Rubidium

**Name of the Vulnerable Software and Affected Versions** OpenTTD versions 1.0.x through 1.0.4 **Description** The issue concerns multiple use-after-free vulnerabilities. These vulnerabilities allow remote attackers to cause a denial of service by abruptly disconnecting during transmission of the map from the server, related to network/network server.cpp, or by forcing a disconnection during the join process, related to network/network.cpp. This can result in an invalid write and daemon crash, or an invalid read and daemon or application crash. **Recommendations** For OpenTTD versions 1.0.x through 1.0.4, update to version 1.0.5 or later to resolve the issue.
