SAP Security Notes, April 2018
Hot News Note 2622660 includes critical security updates for web browser controls delivered with SAP Business Client. The Client provides a unified environment for SAP applications including Fiori, SAP GUI, and Web Dynpro. It supports browser controls from Internet Explorer (IE) and Chrome for displaying HTML content. Security corrections for the WebBrowser control of the .NET framework in IE are delivered directly by Microsoft. Unlike IE, the browser control for Chrome is embedded in SAP Business Client using the open source Chromium Embedded Framework (CEF). Security fixes are provided by the Chromium project and delivered by SAP through periodic Security Notes. Note 2622660 includes corrections addressed by Chromium releases 64 and 65. The critical rating of the note is due to the fact that the highest CVSS rating of the security corrections bundled in the fixes is 9.8/10.
