Descriptions

The issue was addressed with improved checks. This issue is fixed in iPadOS 17.7.4, macOS Ventura 13.7.3, macOS Sonoma 14.7.3, visionOS 2.2, tvOS 18.2, watchOS 11.2, iOS 18.2 and iPadOS 18.2, macOS Sequoia 15.2. Processing web content may lead to a denial-of-service.

This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Apple macOS. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the WindowServer component. The issue results from the lack of proper validation of user-supplied data, which can result in an excessively long loop. An attacker can leverage this vulnerability to create a denial-of-service condition on the system.

macOS Sonoma 14.7.3 addresses bypass, code execution, integer overflow, out of bounds read, and out of bounds write vulnerabilities.
