The CClient::ProcessServerPacket method in engine/client/client.cpp in Teeworlds before 0.6.4 allows remote servers to write to arbitrary physical memory locations and possibly execute arbitrary code via vectors involving snap handling.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
