Lecture (48kB PDF)
Paper (216kB PDF) (72kB gzipped PS) (88kB gzipped DVI) (13kB gzipped TeX).

The ISO/IEC 9796:1991 standard has since been withdrawn, but can still be purchased.
A free online source is section 11.3.5 in the excellent Handbook of Applied Cryptography.

I announced the attack on August 30, 1999 in an sci.crypt.research post.
Here is the mentioned file with messages allowing the attack. Same gzipped, for hash verification purposes.
