description:
pkg_install-20090422:
Consider EOF during signature scan a fatal error. At the very least, the
package is missing the +CONTENTS file at that point. Correctly reset the
entry pointer in that case and make the meta data extraction stricter,
avoiding NULL dereferences for invalid archives.
Fixes pkg_info -X crash on empty files as reported by Daniel Horecki.
