Although RFC 3279 allows both, per RFC 5912, keys must use a named curve
rather than spelling out the curve parameters. Although we do not allow
arbitrary curves, we do have to (pretty hackishly) recognize built-in
curves in ECPrivateKeys.
It seems the cause of this was that OpenSSL, unless you set asn1_flag on
the EC_GROUP, likes to encode keys by spelling out the parameters. This
is in violation of RFC 5915, though probably not in violation of one of
the other redundant ECC specifications. For more fun, it appears
asn1_flag defaults to *off* in the API and *on* in the command-line
tools.
I think the original cause was these defaults meant the pre-BoringSSL
Android/OpenSSL Chromium port wrote out Channel ID keys in this format.
By now this should no longer by an issue, but it'll warrant a bit more
investigation to be sure we can drop it.
For now, keep this logic out of SPKIs by not calling d2i_ECParameters.
d2i_ECParameters is a fairly pointless function when only named curves
are allowed. In testing other implementations, none of Firefox, Safari,
or IE11/Win will parse such certificates (i.e. the error is fatal and
unbypassable). Likewise, because Mac and Windows' underlying libraries
reject this, Chrome on Mac and Windows already rejects such things. Thus
this change should be compatible.
The following is the certificate and key I constructed to test with:

OpenSSL accepts both OID 2.5.8.1.1 and OID 1.2.840.113549.1.1.1 for RSA
public keys. The latter comes from RFC 3279 and is widely implemented.
The former comes from the ITU-T version of X.509. Interestingly,
2.5.8.1.1 actually has a parameter, which OpenSSL ignores:
rsa ALGORITHM ::= {
KeySize
IDENTIFIED BY id-ea-rsa
}
KeySize ::= INTEGER
Remove support for 2.5.8.1.1 completely. In tests with a self-signed
certificate and code inspection:
- IE11 on Win8 does not accept the certificate in a TLS handshake at
all. Such a certificate is fatal and unbypassable. However Microsoft's
libraries do seem to parse it, so Chrome on Windows allows one to
click through the error. I'm guessing either the X.509 stack accepts
it while the TLS stack doesn't recognize it as RSA or the X.509 stack
is able to lightly parse it but not actually understand the key. (The
system certificate UI didn't display it as an RSA key, so probably the
latter?)
- Apple's certificate library on 10.11.2 does not parse the certificate
at all. Both Safari and Chrome on Mac treat it as a fatal and
unbypassable error.
- mozilla::pkix, from code inspection, does not accept such
certificates. However, Firefox does allow clicking through the error.
This is likely a consequence of mozilla::pkix and NSS having different
ASN.1 stacks. I did not test this, but I expect this means Chrome on
Linux also accepts it.
Given IE and Safari's results, it should be safe to simply remove this.
Firefox's data point is weak (perhaps someone is relying on being able
to click-through a self-signed 2.5.8.1.1 certificate), but it does
further ensure no valid certificate could be doing this.
The following is the 2.5.8.1.1 certificate I constructed to test with.
The private key is key.pem from ssl/test/runner:

For TLS, this machinery only exists to swallow no_certificate alerts
which only get sent in an SSL 3.0 codepath anyway. It's much less a
no-op for SSL 3.0 which, strictly speaking, has only a subset of TLS's
alerts.
This gets messy around version negotiation because of the complex
relationship between enc_method, have_version, and version which all get
set at different times. Given that SSL 3.0 is nearly dead and all these
alerts are fatal to the connection anyway, this doesn't seem worth
carrying around. (It doesn't work very well anyway. An SSLv3-only server
may still send a record_overflow alert before version negotiation.)
This removes the last place enc_method is accessed prior to version
negotiation.

This removes the various non-PRF checks from SSL3_ENC_METHOD so that can
have a clearer purpose. It also makes TLS 1.0 through 1.2's
SSL3_ENC_METHOD tables identical and gives us an assert to ensure
nothing accesses the version bits before version negotiation.
Accordingly, ssl_needs_record_splitting was reordered slightly so we
don't rely on enc_method being initialized to TLS 1.2
pre-version-negotiation.
This leaves alert_value as the only part of SSL3_ENC_METHOD which may be
accessed before version negotiation.
