A potential domain bypass transient execution vulnerability was discovered on some Intel Atom® processors that uses a microarchitectural incidental channel. Currently this channel can reveal supervisor data in the L1 cache and the contents of recent stores. As a consequence, this issue may allow an authenticated user to potentially enable information disclosure via local access.

A vulnerability has been identified in SIMATIC ET 200SP Open Controller (incl. SIPLUS variants) (V20.8), SIMATIC S7-1500 Software Controller (V20.8). The web server of the affected products contains a vulnerability that could allow a remote attacker to trigger a denial-of-service condition by sending a specially crafted HTTP request.
