<PRE>[ Shameless ping ]
Is there any progress with the release?
Or any indication about when it could take place?
>><i> 2) Potential DoS when importing an RSA key (segfault of the interpreter)
</I>
><i> > I assume you mean the floating-point exception that occurs when you pass
</I>><i> an
</I>><i> > even modulus to RSA.construct?
</I>><i>
</I>><i> Correct.
</I>><i>
</I>><i> > <A HREF="https://bugs.launchpad.net/pycrypto/+bug/1193521">https://bugs.launchpad.net/pycrypto/+bug/1193521</A>
</I>><i> > <A HREF="https://github.com/dlitz/pycrypto/pull/50">https://github.com/dlitz/pycrypto/pull/50</A>
</I>><i> >
</I>><i> > On pull request #50 ("Add checks to verify correctness of RSA/DSA/ElGamal
</I>><i> > keys"), it would be helpful if others could chime in about the potential
</I>><i> for
</I>><i> > leaking private keys via timing side-channels.
</I>><i>
</I>><i> In addition to fixing the DoS, PR #50 also replaced the custom
</I>><i> KeyFormatError exception with ValueError in the DSA code (I wrote it
</I>><i> before you expressed preference for not having custom exceptions at
</I>><i> all).
</I>><i>
</I>><i> I would actually apply first this other PR:
</I>><i>
</I>><i> <A HREF="https://github.com/dlitz/pycrypto/pull/71">https://github.com/dlitz/pycrypto/pull/71</A>
</I>><i>
</I>><i> Since there are 2 other exception types to fix.
</I>><i> Hopefully PR #50 still applies cleanly after it.
</I>><i>
