Make Sure to Update: iOS 18.1.1 and macOS Sequoia 15.1.1 Fix Actively Exploited Vulnerabilities

by

The iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1 updates that Apple released today address JavaScriptCore and WebKit vulnerabilities that Apple says have been actively exploited on some devices.

bug security vulnerability issue fix larry
With the JavaScriptCore vulnerability, processing maliciously crafted web content could lead to arbitrary code execution. The WebKit vulnerability had the same issue with maliciously crafted web content, and it could lead to a cross site scripting attack.

Apple says that it is aware of reports that these two issues may have been actively exploited on Intel-based Mac systems. While the vulnerabilities are only known to have impacted older Macs, other devices are vulnerable to attack because they have the same security flaws.

For that reason, it is a good idea to update your devices to the latest software as soon as possible.

Whatever happened to those Rapid Security Response patches they were supposed to be able to deploy quickly? Are those being used? I see so many urgent system updates, but I can't remember getting a Rapid Security Response thing automatically.

Do these vulnerabilities affect iOS 17.x.x and macOS 14.x.x?

And yet, ads on iOS can open a browser without our authorization if we touch anywhere on their full-screen videos, or touch one pixel outside their tiny 16×16 pixels "close" button.

Apple really needs to take over the ads with their own standard interface layered on top of the ads, and prompt us if we really want to open a URL in the browser.

They didnt fix any bugs....I feel like they just pushed it out for Thanksgiving. IOS 18 has been a mess. Messed up icloud storage (doesn't collabrate the correct number), issues with messages app where messages show up as group text when its only 1 single text between me and 1 other person. The list goes on and on. I bet the notes app isn't fixed either

I guess there is a particularly high bar of severity in order to justify deploying a rapid response fix. This type of automatic, forced update is high-risk, as demonstrated by the CrowdStrike incident earlier this year. Apple would need to be certain that any exploit is severe enough and urgent enough to justify the potential downsides.
