| When launching the game, multiple chunks from the save file are parsed and copied to a large heap buffer. When parsing PSS data (acquaintances, passerby) the game copies each entry to the heap buffer, the number of entries to copy is read from the end of the multiple pss data chunks and is not checked, leading to an overflow. The "PSS data - friends" chunk is vulnerable too, but the overflow occurs on the stack and unfortunately this isn't exploitable because of a 4 bytes uncontrolled value (in each entry) that gets written on sensitive data.
