This vulnerability could potentially allow an attacker to execute arbitrary code on the affected system. In addition to security enhancements, the update also resolves a specific issue where an infinite loop could occur when a thread enters the Common Language Runtime (CLR) for the first time. Users are advised to ensure that all prerequisite updates are installed prior to applying this rollup to avoid installation issues.
General Sentiment
