Yes, it is correct.

The history of this attack is quite strange: it was known for a long
time by a few crypto people (you can find a reference in Lars Knudsen's
PhD thesis, written in 1994, for instance), but until quite recently, it
was not known in a larger public. Now, everybody seems to know about it
:-)

See for instance http://lasecwww.epfl.ch/birthday.shtml for some details
about its implementation.

A+
