## Affected

- `binutils < 2.34`
- `fedora = 32`
- `cloud_backup`
- `ontap_select_deploy_administration_utility`
- `solidfire,_enterprise_sds_&_hci_storage_node`
- `solidfire_&_hci_management_node`
- `brocade_fabric_operating_system_firmware`
- `hci_compute_node_firmware`

## Remediation

Upgrade past the affected range:

- `binutils 2.34`
