Apple on Monday updated several of its recent security advisories to add new iOS and macOS vulnerabilities, including ones belonging to a new class of bugs.
The iOS 16.3 and macOS Ventura 13.2 advisories, originally released on January 23, have been updated to add three vulnerabilities. One of them is CVE-2023-23520, a race condition affecting the crash reporter component, which can allow an attacker to read arbitrary files as root.
The other two security holes impact the ‘foundation’ component in Apple’s operating systems and they can allow an attacker to “execute arbitrary code out of its sandbox or with certain elevated privileges”, according to the tech giant.
These vulnerabilities, tracked as CVE-2023-23530 and CVE-2023-23531, were reported to Apple by extended detection and response (XDR) company Trellix.
Trellix published a blog post on Tuesday to describe these flaws, which the firm says are part of a new class of bugs that can allow attackers to bypass code signing on macOS and iOS systems.
Trellix’s analysis builds on previous research and exploits that were actually used in the wild to target Apple customers. The company says CVE-2023-23530 and CVE-2023-23531 have opened a “huge range of potential vulnerabilities” that its researchers are currently investigating.
