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 Signed-off-by: Richard Purdie --- diff --git a/meta/recipes-core/meta/cve-update-db-native.bb b/meta/recipes-core/meta/cve-update-db-native.bb index 25ec6bac71d..e5822cee586 100644 --- a/meta/recipes-core/meta/cve-update-db-native.bb +++ b/meta/recipes-core/meta/cve-update-db-native.bb @@ -139,7 +139,12 @@ def parse_node_and_insert(c, node, cveId): for cpe in node.get('cpe_match', ()): if not cpe['vulnerable']: return - cpe23 = cpe['cpe23Uri'].split(':') + cpe23 = cpe.get('cpe23Uri') + if not cpe23: + return + cpe23 = cpe23.split(':') + if len(cpe23) < 6: + return vendor = cpe23[3] product = cpe23[4] version = cpe23[5]
