OpenRC opentmpfiles through 0.1.3, when the fs.protectedhardlinks sysctl is turned off, allows local users to obtain ownership of arbitrary files by creating a hard link inside a directory on which "chown -R" will be run.

Buffer overflow in src/openttd.cpp in OpenTTD before 0.6.2 allows local users to execute arbitrary code via a large filename supplied to the "-g" parameter in the ttdmain function. NOTE: it is unlikely that this issue would cross privilege boundaries in typical environments.

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."

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.

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.

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.

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.
