SteamWrap_FileRead buffer overflow

[maaniv]

Function SteamWrap_FileRead code do not put zero to end of string char *bytesData = (char *)malloc(length); int32 result = SteamRemoteStorage()->FileRead(fName, bytesData, length);

value returnValue = alloc_string(bytesData);

Must be char *bytesData = (char *)malloc(length + 1); int32 result = SteamRemoteStorage()->FileRead(fName, bytesData, length); *(bytesData + length) = 0;

value returnValue = alloc_string(bytesData);

I believe using alloc_string_len might fix this: https://github.com/larsiusprime/SteamWrap/issues/10

I'm working on a patch.
