Thanks for sharing the link to the NDSS paper. The paper only
seems to be talking about two issues (as you may have noticed
we reported several others) -
1. GnuTLS ignores path length constraints for version <3.0.
I think it's a different bug than the one we described even
though the result is the same. We found the bug in GnuTLS
3.1.9 that (unlike older versions) has code for parsing path
length constraints but does not enforce it correctly. Please
see my earlier email to the gnutls-devel mailing list for
2. GnuTLS accepts certificates with unknown critical extensions.
This seems to be the same bug that you reported.
