However, the patched vulnerabilities also affected malicious web content that could lead to the execution of arbitrary code. Apple says these were actively exploited.<\/strong><\/p>\n\n\n\n<p>Apple today released iOS 14.5.1, iPadOS 14.5.1, watchOS 7.4.1, macOS Big Sur 11.3.1 as well as iOS 12.5.3 and iPadOS 12.5.3 <a href=\"https:\/\/www.apfelpatient.de\/en\/news\/ios-14-5-1-and-more-apple-releases-new-updates\">published<\/a>, with the changes being primarily security fixes.

According to Apple, the problem was fixed with &quot;improved state management.&quot; A second bug affected the same potential for malicious web content that can lead to arbitrary code execution. According to the company, this vulnerability was also exploited. In this case, Apple fixed the problem with an integer overflow and &quot;improved input validation.&quot; The documentation states the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-webkit\">WebKit<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)<\/li><li>Impact: Processing maliciously crafted web content may lead to arbitrary code execution.
