NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Apple Releases Critical Security Updates for Mac OS X, iOS, watchOS, and Other Applications
Description: Apple has released seven security bulletins to address a variety of vulnerabilities that have been identified in various software platforms such as Mac OS X, iOS, watchOS, iTunes, and Safari. Several vulnerabilities in OS X, iOS and watchOS are deemed critical as they are remotely code execution flaws which could be exploited through a maliciously crafted image file sent via MMS. Many other critical and important vulnerabilities were also addressed in these bulletins. Users are advised to install these security updates as soon as possible.
