Apple has patched a security vulnerability that allowed hackers to build a jailbreak tool allowing deep access to the iPhone software.
In a security advisory, Apple acknowledged that it had fixed the vulnerability in iOS 13.5.1, posted Monday. The technology giant credited the unc0ver team, which released the jailbreak just last week, for finding the vulnerability.
Although details of the vulnerability are not yet public, Apple typically works quickly to patch vulnerabilities that allow jailbreaks, fearing that the same vulnerability could also be abused by malicious hackers.
In a tweet, one of the lead jailbreakers confirmed that updating to iOS 13.5.1 will close the vulnerability and render the jailbreak useless.
Jailbreaking is a popular way to allow users to break free from Apple’s “jail” — hence the term — that prevents deep access to an iPhone’s operating system. Apple has does this to improve device security and to reduce the surface area in which hackers can attack the software. But jailbreakers say breaking through those restrictions allows them greater customization over their iPhones in a way that most Android users are already used to.
Security experts typically advise against jailbreaking as it can expose a device owner to a greater range of attacks, while advising users to install their devices and software as soon as update become available.
Apple said iOS 13.5.1 also comes with new Memoji stickers and other bug fixes and improvements.
Update today. If security isn’t your thing, at least do it for the Memoji stickers.
