Apple Security updates May 2017 fixed 141 vulnerabilities across multiple products including macOS Sierra, iOS, watchOS, tvOS, iCloud, Safari, and iTunes. However, most of the vulnerabilities exist in some instances with root privileges (41 in iOS 41, 37 in macOS Sierra, 23 in tvOS, and 12 in watchOS) and could lead to arbitrary code execution. A reliable vulnerability management tool can prevent these attacks.

Apple Security updates May 2017 also fixed 26 vulnerabilities in the Safari browser, which could lead to arbitrary code execution. Moreover, the rest of the vulnerabilities could lead to universal cross-site scripting, the exfiltration of data cross-origin, application termination, and spoofing. However, Out of 26, 23 vulnerabilities exist in the WebKit web browser engine. A patch management solution can mitigate these vulnerabilities.

Apple also fixed arbitrary code execution vulnerabilities in iCloud and iTunes for Windows.

Patch Analysis & Exploitation Timeline: Critical WSO2 and Adobe Flaws Show 1-Day vs. 133-Day Exploitation Window , September 24, 2026 KEV Additions

Two critical vulnerabilities added to CISA KEV on September 24, 2026 reveal sharply different exploitation timelines. CVE-2026-71362 saw publicly documented exploitation roughly one day after Adobe's patch release, while CVE-2026-5430 had a 133-day vendor-remediation-to-observed-exploitation interval.
