[openssl-dev] [openssl.org #4430] #1852: [BUG] Invalid Proxy Certificates Pass Validation

My view is that code should follow the RFC (in this case RFC3820) where possible, and hence this should be put in the queue as higher priority - especially since it could have potential security implications.

The same behaviour is present in all releases including master.
I don't see any code in OpenSSL that imposes any constraints on
the subject names of proxy certificates.

If strict adherence to the rules in RFC3820 is important for security
(I don't where proxy certs are used and what real semantics
applications expect), then this issue remains to be addressed.

Perhaps reopen this one.
