I don't remember when we started, but we treat all parsing issues that lead to 
crashes or anything worse as security issues and fix retroactively. Since 5.12 
is and has been closed for a while now, it may not have all the fixes; you 
should look at Qt's list of security issues and apply any remaining patches
