CVE-2024-23222Apple WebKit — crafted web content runs code

Crafted web content confuses types in WebKit and executes the attacker's code. Apple brought the January 2024 fix back to older devices that cannot move to the current release, which is why the version list is so long.

YOUR NEXT MOVE

Update Safari to 17.3, or the device to iOS 17.3, 16.7.5 or 15.8.7, macOS Sonoma 14.3, Ventura 13.6.4 or Monterey 12.7.3.
