Name of the Vulnerable Software and Affected Versions macOS versions prior to 10.13.1

Description The issue involves the CFNetwork component and allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This is due to a heap-based buffer overflow in the CFNetwork component. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.

Recommendations For macOS versions prior to 10.13.1, update to version 10.13.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the CFNetwork component until a patch is available. Avoid using crafted apps that may exploit the heap-based buffer overflow vulnerability in the CFNetwork component.
