TOP VULNERABILITY THIS WEEK: Apple Releases Emergency iOS Update to Address Zero-Day Vulnerabilities Being Exploited in the Wild


NOTABLE RECENT SECURITY ISSUES

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Apple Releases Emergency iOS Update to Address Zero-Day Vulnerabilities Being Exploited in the Wild
Description: Apple has released an emergency security update for iOS after it was discovered that three zero-day vulnerabilities were being exploited in the wild. These three vulnerabilities when used together could be used to achieve remote code execution with kernel level privileges. Citizen Labs and Lookout, research firms that privately disclosed the vulnerabilities to Apple, state that these vulnerabilities were used to install surveillance software on the phones of human rights activists. Users are advised to patch immediately.
