cve-update-db-native: skip on empty cpe23Uri
Recently an entry in the NVD DB appeared that looks like that {'vulnerable': True, 'cpe_name': []}. As besides all the vulnerable flag no data is present we would get a KeyError exception on acccess. Use get method on dictionary and return if no meta data is present Also quit if the length of the array after splitting is less than 6 Signed-off-by: Konrad Weihmann <kweihmann@outlook.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit 00ce2796d97de2bc376b038d0ea7969088791d34) Signed-off-by: Anuj Mittal <anuj.mittal@intel.com>
