So just an Authenticode bypass? Meh. As
@taviso said, nothing like an RCE in PE parsing, not even sure what the NSA would do with this. It might be a fun crypto vuln though!2 proslijeđena tweeta 14 korisnika označava da im se sviđa -

if it requires privileged network active intercept and DNS spoofing for updates, it would be overblown. But as the Zen master said, We'll see...

I was thinking the same too. This could be more than network MITM if client side certificates can be spoofed.

So doesn’t make sense why it’s rated important and not critical. Unless client cert authentication isn’t affected.
