Found with Valgrind while cleaning up the Linux cheat menu code.
The length calculated for
versionSubstringis the number of bytes in the substring, but that did not account for the null terminator necessary when putting the data in its own string allocation. Thus, thesscanfcall could read outsize the allocation bound.The fix is very simple: provide the extra byte necessary to store a null terminator and do so.
