Hi James,

Can you pull these fixes for the ASN.1 compiler and decoder into the
security/next tree and also pass them onto Linus for immediate inclusion?

I've checked that the bugs fixed can't be used to compromise a system, so I
think they're survivable, but all the same, it's best if they're fixed
immediately (if I'm wrong, there's the possibility of handing memcpy() a
NULL pointer).

Here can be found a pair of programs to take BER/DER-encoded X.509 and
PKCS#7 and turn it into text which can be edited and turn the edited text
back into BER.  This allows the ASN.1 to be butchered in interesting ways.
