Apple Patches Four Vulnerabilities in macOS

Apple on Thursday informed customers that it patched a total of four vulnerabilities across macOS Catalina, High Sierra and Mojave.

One of the security holes is CVE-2020-9973, an issue affecting the Model I/O component. Apple says exploitation of the flaw, which involves the processing of a malicious USD file, could lead to arbitrary code execution or a DoS condition.

This vulnerability, reported to Apple by a Cisco Talos researcher, affects all versions of macOS and it was also patched earlier this month in iOS and iPadOS with the release of version 14.

Another vulnerability that impacts all versions of macOS and which Apple also patched in iOS 14 and iPadOS 14 earlier this month is CVE-2020-9968, a sandbox issue that can be exploited by a malicious application to access restricted files. Adam Chester of TrustedSec has been credited for reporting it to Apple.

The tech giant has also patched an arbitrary code execution vulnerability that can be exploited using malicious image files. This issue, identified by Xingwei Lin of Ant Group Light-Year Security Lab, affects the ImageIO component in macOS High Sierra and Mojave.

The fourth issue fixed this week in macOS — it only impacts High Sierra — affects the Mail component and it can allow a remote attacker to “unexpectedly alter application state.” The flaw was discovered by researchers from the FH Münster University of Applied Sciences in Germany.

iCloud for Windows was updated to version 11.4 this week. The latest version fixes a cross-site scripting (XSS) vulnerability.

Apple also released updates for iOS 14, watchOS 7 and tvOS 14 this week, but says they don’t address any vulnerabilities.
