Do not parse Status fields from remote sources
This could allow an attacker to mark a package as installed in a
remote package index, as long as the package was not listed in
the dpkg status file.
This way, an attacker could force the installation of a package
during a dist-upgrade, by providing two packages in an index,
an older marked as installed, and a newer - apt would "upgrade"
to the newer version.
