There's nothing new about the math here. 1024 bit DH has been precarious for over a decade, at least since Tromer costed out an RSA-1024 factoring machine.
In other words, people a decade ago were also telling you to avoid DH-1024. What we're looking at today is a more efficient way of exploiting a bug we've known about for a long time.
