Does Naruto and everyone else know the truth about Itachi? I know that Sasuke, Tobi, Madara, The 3rd Hokage and his 3 old advisers including Danzou know the truth about Itachi, as to why he murdered his own clan barring Sasuke. 

Who else knows about this secret? Is it ever fully revealed publicly, and is Itachi ever stated as the true hero of Konoha?
As previously posted Naruto, Kakashi and Yamato were told all at the same time by Tobi before the 5 kage summit. 

Furthermore, Naruto had a very strong inference to go on when he fought the zombie-like Itachi and Pain in the 4th great shinobi war. 

But the only person who knows of every single full detail is Sasuke as Itachi shared everything with Sasuke when they defeated Kabuto in the 4th great shinobi war arc.
