Description: The issue is an out-of-bound write vulnerability due to insufficient input validation. A remote, unauthenticated attacker may craft an encryption key to the affected products, potentially causing a buffer overflow and services to become abnormal.

Recommendations: For all affected versions, apply the necessary security patches or updates to fix the out-of-bound write vulnerability. As a temporary workaround, consider restricting access to the affected products until a patch is available. Avoid using the affected encryption key in the affected products until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
