Can average users change bug statuses?

[Alberto Salvia Novella]

About (https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1569970), 
an user told me this:

Nicolas Merieux:

The question is, do a Launchpad account have permissions by default to 
change bug statuses to confirmed, or have I been requesting it by mistake?

Thanks.
