Apple released security updates for multiple products, with their patches for critical zero-days vulnerabilities including Safari, Xcode, tvOS, watchOS, iOS, iPadOS, and iTunes. A total of 30 vulnerabilities are addressed, including Arbitrary Code Execution, Denial of Service, Privilege Escalation, Sandbox Escape, and Information Disclosure. Out of these 30 CVEs, 14 vulnerabilities are considered very critical which was shown on their vulnerability scans as they allow an attacker to execute arbitrary code. This is showing itself due to the vulnerability scanning.
On Thursday, Apple took action to address three critical Zero-Day vulnerabilities actively exploited in the wild. These vulnerabilities, identified as CVE-2021-30858, CVE-2021-30860, and CVE-2021-30869, have an impact on a broad range of iPhone and iPad models, including iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad Mini 2, iPad Mini 3, and the sixth-generation iPod touch.
