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 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 ordercmd.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 CMDINSERTORDER command.

The NetworkSyncCommandQueue function in network/networkcommand.cpp in OpenTTD before 1.0.3 does not properly clear a pointer in a linked list, which allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted request, related to the client command queue.

Unspecified vulnerability in the NormaliseTrainConsist function in src/traincmd.cpp in OpenTTD before 0.7.5-RC1 allows remote attackers to cause a denial of service (daemon crash) via certain game actions involving a wagon and a dual-headed engine.

Multiple buffer overflows in OpenTTD before 1.1.3 allow local users to cause a denial of service (daemon crash) or possibly gain privileges via (1) a crafted BMP file with RLE compression or (2) crafted dimensions in a BMP file.
