Timo Kreuzer c5158963a3 [ADVAPI32] Fix a buffer overflow in RegQueryValueExA ... The code was trying to check whether the output string was already NULL terminated by RtlUnicodeToMultiByteN before NULL terminating it by checking DataStr[*count - 1] for a NULL terminator. But since RtlUnicodeToMultiByteSize always returns the size without the NULL terminator, DataStr[*count - 1] would always be the last actual character, never an optional NULL terminator. For 0 sized strings this would actually lead to accessing the output buffer at position -1 (on 32 bit) or 0xFFFFFFFF (on 64 bit). Fix this by removing the check. This fixes a crash in advapi32_winetest:registry on x64.		2023-01-04 10:32:28 +01:00
