A new intermediate release of cvechecker is now released. The tool is reported to build properly on NetBSD and FreeBSD as well (although much user experience there is still welcome), introduces a cvereport command (example output), has lowered its initial dependency requirements and pullcves now only loads the CVE XML changes in the database, rather than iterating across all CVE XML entries.
Many thanks to Nigel Horne for his continuous testing/hammering on the tool.
