Correct.

In addition to fixing the DoS, PR #50 also replaced the custom
KeyFormatError exception with ValueError in the DSA code (I wrote it
before you expressed preference for not having custom exceptions at
all).

I would actually apply first this other PR:

https://github.com/dlitz/pycrypto/pull/71

Since there are 2 other exception types to fix.
Hopefully PR #50 still applies cleanly after it.
