HTTP Negotiate SPNEGO GSS-API and ASN.1 length encoding

0

Hi,

Wireshark does not seem to decode the SPNEGO GSS-API tokens correctly when they don't contain the 0x81 or 0x82 length designator in the ASN.1 DER lengths. If the lengths don't have the upper bit set - which means it's just a byte of length than it isn't decoded.

Well it certainly looks like a bug to me. Can you confirm? I did search the bugs looking to see if it has already been reported but couldn't find anything... Should I just file a bug then?
