While the last iOS 14.3 update brought new camera capabilities to the iPhones, the new iOS 14.4 will address critical security threats in addition to fixing bugs in keyboard and camera hardware in select mobile variants.
It has come to light that hackers may exploit a vulnerability dubbed as 'CVE-2021-1782' to access some sensitive information on iPhones using an application (name not disclosed).
"A malicious application may be able to elevate privileges. Apple is aware of a report that this issue may have been actively exploited," the company said.
Two unnamed security experts had also detected a couple of vulnerabilities-- CVE-2021-1870 and CVE-2021-1871--, wherein remote attackers may be able to cause arbitrary code execution on iPhones. These are also fixed, Apple added.
The new iOS 14.4 update will enable iPhones to detect QR codes in smaller dimensions, also fix keyboard glitches that used to cause delayed typing issues, word suggestions, and some improvements to accessibility features.
