Openttd : Security Vulnerabilities, CVEs, CVSS score >= 6

Multiple buffer overflows in OpenTTD before 1.1.3 allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors related to (1) NAME, (2) PLYR, (3) CHTS, or (4) AIPL (aka AI config) chunk loading from a savegame.

Multiple off-by-one errors in order_cmd.cpp in OpenTTD before 1.1.3 allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted CMD_INSERT_ORDER command.

Multiple use-after-free vulnerabilities in OpenTTD 1.0.x before 1.0.5 allow (1) remote attackers to cause a denial of service (invalid write and daemon crash) by abruptly disconnecting during transmission of the map from the server, related to network/network_server.cpp; (2) remote attackers to cause a denial of service (invalid read and daemon crash) by abruptly disconnecting, related to network/network_server.cpp; and (3) remote servers to cause a denial of service (invalid read and application crash) by forcing a disconnection during the join process, related to network/network.cpp.

OpenTTD before 1.0.1 does not properly validate index values of certain items, which allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted in-game command.

OpenTTD before 1.0.1 accepts a company password for authentication in response to a request for the server password, which allows remote authenticated users to bypass intended access restrictions or cause a denial of service (daemon crash) by sending a company password packet.

Buffer overflow in the TruncateString function in src/gfx.cpp in OpenTTD before 0.6.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted string. NOTE: some of these details are obtained from third party information.

Buffer overflow in the server in OpenTTD 0.6.1 and earlier allows remote authenticated users to cause a denial of service (persistent game disruption) or possibly execute arbitrary code via vectors involving many long names for "companies and clients."

Multiple buffer overflows in OpenTTD before 0.4.0.1 allow attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

Multiple format string vulnerabilities in OpenTTD before 0.4.0.1 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
