Security researchers have released the proof-of-concept for four exploitable flaws in Apple’s iOS that would allow anyone with enough skill to target a device and execute malicious code remotely.
Of the four flaws disclosed by Google’s team of researchers, CVE-2019-8646 is of importance because it can allow an attacker to read the content of files stored on iOS devices remotely, without requiring the user’s interaction. All the attacker has to do is send the device owner a maliciously-crafted iMessage.
The researchers have actually found a fifth vulnerability, similar to the one described above, that can also be executed by just sending a malformed iMessage. However, the PoC for this flaw is still under wraps as the latest iOS update fails to completely patch it.
With the PoCs now out, iPhone owners are urged to download and install iOS 12.4 sooner rather than later. According to the release notes, the update also introduces iPhone migration to directly transfer data from an old iPhone to a new iPhone, as well as enhancements to Apple News+. The update further includes a security fix for the Walkie-Talkie app on Apple Watch and re-enables Walkie-Talkie functionality.
