> You mean to tell us that nmap is currently segfaulting for an industry
No, it is not segfaulting, and it is not exploitable. Our libc contains a feature to detect backwards memcpy, in that case it logs and KILLS THE PROCESS dead. There is no way to consider this a risk. The problem here is that nmap had a bug like this, in this decade. The other problem is that dynamic checks, and static checks, didn't find a problem which is so visible before it shipped.
