There seem to be 2 obvious workarounds:

1. Don't load mod_setenvif. That's where the problem lies - if the
vulnerable code isn't loaded then your application isn't vulnerable.

2. Don't use .htaccess files. Neither vulnerability can be triggered
if you AllowOverride None. This is good for security anyway and if you
are dealing with PCI related data I'd recommend this regardless of any
issues in the code. It'll also be more efficient.
