As mentioned in the advisory, the devices eligible for this update include iPhone 6s and later, iPad Air 2 and later, iPad Pro (all models), iPad 5th gen and later, iPad mini 4 and later, and iPod touch (7th gen).

Though, iOS 15 users shouldn’t worry about this vulnerability since Apple has already patched it for them. Earlier this month, Apple released the iOS 15.0.2 emergency update fixing this bug.

Alongside this zero-day, iOS 14.8.1 also addresses numerous other vulnerabilities. A majority of these bugs could allow arbitrary code execution.

Some of these include CVE-2021-30907 – an integer overflow affecting audio that could lead to privilege escalation, CVE-2021-30917 – a memory corruption flaw that could allow arbitrary code execution by processing maliciously crafted image, CVE-2021-30919 – an out-of-bounds write leading to arbitrary code execution by processing malicious PDFs, and CVE-2021-30918 – a lock screen problem that allowed viewing restricted content from Lock Screen.

Apple addressed these issues following reports from different researchers. Now it’s up to the users to update their devices at the earliest.

Analytics

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
