Hello,

while working on StarForce 3, the service/driver installer bumps on incomplete
QueryServiceConfigA/W().

The service display name is queried to get required buffer size but later
forgotten to query the actual value.
The SF service installer doesnt check the QUERY_SERVICE_CONFIGW string values
for NULL ptrs before access (which is the case for missing display name).

--- snip dlls/advapi32/service.c ---
BOOL WINAPI 
QueryServiceConfigW( SC_HANDLE hService,
                     LPQUERY_SERVICE_CONFIGW lpServiceConfig,
                     DWORD cbBufSize, LPDWORD pcbBytesNeeded)
{

 ...
 /* now do the strings */
    p = (LPBYTE) &lpServiceConfig[1];
    n = total - sizeof (QUERY_SERVICE_CONFIGW);
  ....

   sz = n;
    r = RegQueryValueExW( hKey, szGroup, 0, &type, p, &sz );
    if( ( r == ERROR_SUCCESS ) || ( type == REG_SZ ) )
    {
        lpServiceConfig->lpLoadOrderGroup = (LPWSTR) p;
        p += sz;
        n -= sz;
    }

    /* +++ */
    sz = n;
    r = RegQueryValueExW( hKey, szDisplayName, 0, &type, p, &sz );
    if( ( r == ERROR_SUCCESS ) || ( type == REG_SZ ) )
    {
        lpServiceConfig->lpDisplayName = (LPWSTR) p;
        p += sz;
        n -= sz;
    }
    /* +++ */
   ...

    /* +++ */
    TRACE("Display name = %s\n", debugstr_w(lpServiceConfig->lpDisplayName) );
    /* +++ */
}

--- snip dlls/advapi32/service.c ---

With service display name correctly filled in, the installer is happy at this stage.

Regards
