According to The Verge, when an older device and software get a security update, “it’s understandable that it’s a serious issue and should take the time to do so.”
Apple’s announcement said that iOS 12.5.6 will fix the issue of WebKit, which currently exists a vulnerability that allows malicious websites to run unchecked code, if the user opens the website with Safari or another some browser. The company also warned that the vulnerability “could have been exploited”, but did not detail the attacks.
To update, users go to Settings > General > Software Update. This version is nearly 300 MB in size. Since older devices often have low memory capacity, users may need to free up memory before doing so.
iPhone 5s is the oldest device still supported by Apple. Product launched in 2013, equipped with A7 chip, 1 GB RAM and 4-inch screen. The last time this iPhone model was updated was September 2021. Apple then released iOS 12.5.5 to fix a security bug related to the risk of attacks via PDF files.
The highest operating system version for iOS devices today is iOS 15.6.1, released in mid-August to also patch security holes.
