The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.

libopenssl-1_1-devel-1.1.1m-4.1 on GA media

A new LTS Firmware release fixes known vulnerabilities in used open-source libraries. In addition, the following improvements have been implemented: HMI - Hardening against DoS attacks. - Hardening against memory leak problems in case of network attacks. WBM - Umlauts in the password of the 'User Manager' were not handled correctly. The password rule for upper and lower case was not followed. This could lead to unintentionally weaker passwords.- Hardening of WBM against Cross-Site-Scripting. User Manager - In security notifications 'SecurityToken' was always displayed as '0000000' when creating or modifying users.- Hardening of Trust and Identity Stores.

Critical vulnerabilities have been discovered in the product due to outdated software components.The impact of the vulnerabilities on the affected device may result in
