permission problem since MySQL 5.6.37 update

Hello,

I was running MySQL 5.5 and I was able to export results of MySQL queries into a file using "INTO OUTFILE". Everything was fine.
Then I updated to MySQL 5.6 last days (for some reasons) and now, when I run the same queries, it gives me the error : "Can't create/write to file '/home/account/dir/dir2/filename.csv' (Errcode: 13 - Permission denied)".

I tried using "INTO OUTFILE 'filename.csv'" instead of "INTO OUTFILE '/home/account/dir/dir2/filename.csv'" and it worked ! But I can't understand the problem since dir2 has 777 permissions...

What's the problem now ?? Why MySQL is unable to write this file ??

Thanks in advance for your help,

T.
