- **Availability:** High (DoS risk for IceWall products)
## Remediation
### Patches
HPE recommends upgrading to the following versions:
- **Aruba ClearPass:** Upgrade to versions higher than 6.11.14 or 6.12.8 as specified in HPESBNW05130.
- **HPE IceWall:** Refer to bulletins HPESBMU05142 and HPESBMU05147 for specific version-dependent hotfixes.
### Workarounds
