**Description**
The issue involves the Safari component and allows remote attackers to spoof an HTTP authentication sheet or cause a denial of service via a crafted web site. It is related to insufficient access control in the Safari browser and iOS operating system, which can be exploited by a remote attacker to bypass HTTP authentication or cause a denial of service using a specially crafted website.

For Safari versions prior to 10.1, update to version 10.1 or later to resolve the issue.
