Apple is urging iPhone and iPad users to promptly update their operating systems to fix security bugs that may have already been exploited by hackers.
On its support webpage, the company said three security holes “may have been actively exploited.” He did not reveal too many specifics about the bugs, noting that “Apple does not disclose, discuss or confirm security issues until an investigation has been carried out and patches or versions are available.”
The problem is a link in an exploit chain, which means that a hacker would need to exploit additional bugs to be fully executable. The company declined to comment further on any attacks.
The company released security patches on Tuesday as part of its new iOS 14.4 software, which also includes fixes for keyboard lag and allows for smaller QR codes to be read from the camera.
Apple said two security concerns stem from its WebKit, an open source browser engine used by Safari and iOS browsers. “A remote attacker may be able to cause arbitrary code execution,” the company said in its description notes. Meanwhile, Kernel, an Apple developer framework, has also been affected.
The exploits were reported by “an anonymous researcher,” according to the web page.
Apple prides itself on device security but is not immune to exploits. Last year, Google researchers found several websites with code that allowed hackers to silently infiltrate iPhones. Meanwhile, an iOS13 bug revealed contact details stored in iPhones without requiring a passcode or biometric identification, a flaw the company did not publicly address until several months after its first report.
