As a result, even if the user specifies to listen only on localhost (e.g. `-netdev user,hostfwd=tcp:127.0.0.1:22-:22`), qemu will listen on `*.*`. This is a potential security issue (as it may unexpectedly expose the guest to internet or local network traffic). +Additional information: +The bug is here: https://gitlab.com/qemu-project/qemu/-/blob/master/net/slirp.c#L777 + +Rather than hardcoding `INADDR_ANY`, qemu should respect the user-defined bind address. |
