[gnutls-devel] libtasn1 | Potential Buffer Overrun in _asn1_tag_der() (#49)

[Read-only notification of GnuTLS library development activities]

Given that this function only handle 0-3 byte lengths, I think it can be implemented in a more readable style without the double loops, and that we should do that.  I haven't been able to convince myself if there ever is any situation where the tag value comes from attacker-controlled data.
