AI Summary

GlobalSign opened this bug to request embedding of its ECC root certificates (“GlobalSign Root CA - R4” and “GlobalSign Root CA - R5”) into Mozilla’s root store. The submission included requested trust bits and technical details for both roots, along with URLs for the root certificates and a test site. GlobalSign later withdrew the application, stating that Symantec engineering reviewed the ECC roots and offline highlighted a potential flaw involving encoded null values. GlobalSign said it would recreate the roots and re-submit, and asked for a new bug when ready. A Mozilla participant questioned why GlobalSign believed the issue was not a problem for RFC 5758, citing RFC language and pointing out that the roots (and the end-entity test certificates) included NULL parameters. GlobalSign responded that browsers had accepted the certificates despite non-compliance and clarified that it agreed the roots should respect RFC 5758 and would re-cut them. The bug is currently resolved as WONTFIX.
