CVE-2016-9400
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
