description:
A vulnerability exists in the Relion update package signature validation. A tampered update package could cause the IED to restart. After restart the device is back to normal operation.
An attacker could exploit the vulnerability by first gaining access to
the system with security privileges and attempt to update the IED
with a malicious update package. Successful exploitation of this
vulnerability will cause the IED to restart, causing a temporary Denial of Service.
