Severity: 2-Critical


CA certificates with long but different serial numbers are treated identical and duplicate, thus get lost in the CA certificate merge operation. Only one would be left.


Certificates with large serial numbers are treated as duplicate, and removed.


- The CA bundle file is managed by the CA bundle manager. - The file contains certificates with large serial numbers.


There is no workaround at this time.

Fix Information

Large serial numbers are treated correctly.
