Title:	OpenTTD 'NetworkSyncCommandQueue()' Denial of Service Vulnerability
Summary:	OpenTTD is prone to a denial of service (DoS) vulnerability.
Description:	Summary: OpenTTD is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: The flaw is due to the 'NetworkSyncCommandQueue()' function in 'src/network/network_command.cpp' not properly resetting the 'next' pointer, which can be exploited to trigger an endless loop and exhaust CPU resources when joining a server. Vulnerability Impact: Successful exploitation will allow remote attackers to cause the application to fall into an infinite loop, denying service to legitimate users. Affected Software/OS: OpenTTD version 1.0.2 and prior. Solution: Upgrade to the latest version of OpenTTD 1.0.3 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
