Summary
go-ntlmssp NTLM challenges can panic on malformed payloads
Details

go-ntlmssp is a Go package that provides NTLM/Negotiate authentication over HTTP. Prior to version 0.1.1, a malicious NTLM challenge message can causes an slice out of bounds panic, which can crash any Go process using ntlmssp.Negotiator as an HTTP transport. Version 0.1.1 patches the issue.
