Subject: Re: Security advisory for musl libc - stack-based buffer overflow in
 ipv6 literal parsing [CVE-2015-1817]


I think Dropbear probably is vulnerable to CVE-2015-1817
post-authentication. TCP forwarding requests will call
(moved to netio.c in head, and PF_UNSPEC has been fixed to
AF_UNSPEC). Pre-authentication should be OK, only
getnameinfo() is called (if that's enabled).

musl's network-facing DNS code seems a bit precarious with
pointer arithmetic?
