Better yet: DON'T use the bundled libraries. 

Always use system libraries so that they are updated by the system. If that's 
not possible, then build the third party libraries yourself before Qt and 
install them to your target so they appear to be system libraries from Qt's 
perspective. In this case, you're responsible for tracking the security issues 
for all those libraries yourself.

Qt does not usually provide security fixes for issues in third-party content, 
unless they are caused by our own use of those libraries.
