Affected by this vulnerability is the function SQFuncState::PopTarget of the file src/squirrel/squirrel/sqfuncstate.cpp. Executing a manipulation of the argument _target_stack can lead to out-of-bounds read. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized.
