Apple on Monday backported fixes for an actively exploited security flaw to older iPhone and iPad models. The issue, tracked as CVE-2023-23529, concerns a type confusion bug in the WebKit browser engine that could lead to arbitrary code execution.

Apple has released security updates to backport patches released last month, addressing an actively exploited zero-day bug for older iPhones and iPads. "Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited," Apple describes the zero-day.

Hackers continue to target zero-day vulnerabilities in malicious campaigns, with researchers reporting that 55 zero-days were actively exploited in 2022, most targeting Microsoft, Google, and Apple products. According to Mandiant, most of last year's zero-day flaws were exploited by Chinese state-sponsored actors and most concerned operating systems, web browsers, and network management products.

Apple has revised the security advisories it released last month to include three new vulnerabilities impacting iOS, iPadOS, and macOS. The first flaw is a race condition in the Crash Reporter component that could enable a malicious actor to read arbitrary files as root. "An app may be able to execute arbitrary code out of its sandbox or with certain elevated privileges," Apple said, adding it patched the issues with "Improved memory handling."

Apple this week released bug-splatting updates to its operating systems and Safari browser, to fix a zero-day vulnerability in its WebKit browser engine that's reported to have been actively exploited. Apple's advisory says the company "Is aware of a report that this issue may have been actively exploited." It credits an anonymous researcher for reporting the bug and its iOS advisory also acknowledges "The Citizen Lab at The University of Toronto's Munk School for their assistance."

Apple has just released updates for all supported Macs, and for any mobile devices running the very latest versions of their respective operating systems. Apparently, tvOS recently received a product-specific functionality fix that already used up the version number 16.3.1 for Apple TVs. As we've seen before, mobile devices still using iOS 15 and iOS 12 get nothing, but whether that's because they're immune to this bug or simply that Apple hasn't got round to patching them yet.

Apple has released security updates that fix a WebKit zero-day vulnerability that "May have been actively exploited."The bug has been fixed in iOS 16.3.1 and iPadOS 16.3.1, macOS Ventura 13.2.1, Safari 16.3.1, and possibly also in tvOS 16.3.2 and watchOS 9.3.1 - though release notes for the updates for those Internet of Things operating systems have been temporarily witheld.

Apple on Monday rolled out security updates for iOS, iPadOS, macOS, and Safari to address a zero-day flaw that it said has been actively exploited in the wild. It's not immediately clear as to how the vulnerability is being exploited in real-world attacks, but it's the second actively abused type confusion flaw in WebKit to be patched by Apple after CVE-2022-42856 in as many months, which was closed in December 2022.

Apple has released emergency security updates to address a new zero-day vulnerability used in attacks to hack iPhones, iPads, and Macs. The zero-day patched today is tracked as CVE-2023-23529 [1, 2] and is a WebKit confusion issue that could be exploited to trigger OS crashes and gain code execution on compromised devices.
