TITLE

Apple macOS ModelIO USD Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

DESCRIPTION

This issue was addressed with improved checks. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, iOS 14.4 and iPadOS 14.4. Processing a maliciously crafted image may lead to heap corruption. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. Interaction with the ModelIO library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the ModelIO framework. Crafted data in a USD file can trigger a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Apple IO Model is a module of Apple (Apple) for processing IO operations. A code issue vulnerability exists in Apple macOS that arises from a boundary error within the Model I/O component in macOS. A remote attacker could deliver a specially crafted file, trick the victim into opening the file, trigger a heap-based buffer overflow and execute arbitrary code on the target system. Vulnerabilities exist in the following products or versions: macOS 10.3, macOS 10.12.4, macOS 10.12.5, macOS 10.12.6, macOS 10.12.6.2, macOS 10.13, macOS 10.13.1, macOS 10.13.2, macOS 10.13.3, macOS 10.13 .4, macOS 10.13.5, macOS 10.13.6, macOS 10.14, macOS 10.14.1, macOS 10.14.2, macOS 10.14.3, macOS 10.14.4, macOS 10.14.5, macOS 10.14.6, macOS 10.15, macOS 10.15 SU1, macOS 10.15.1, macOS 10.15.2, macOS 10.15.3, macOS 10.15.4, macOS 10.15.4 SU1, macOS 10.15.5, macOS 10.15.5 SU1, macOS 10.15.6, macOS 10.15.6 SU1 , macOS 10.15.7, macOS 10.15.7 SU1, macOS 11.0, macOS 11.0.1, macOS 11.1. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2021-02-01-2 Additional information for APPLE-SA-2021-01-26-1 iOS 14.4 and iPadOS 14.4 iOS 14.4 and iPadOS 14.4 addresses the following issues.
