A validation issue was addressed with improved input sanitization. This issue is fixed in macOS Catalina 10.15.3. An application may be able to read restricted memory. This vulnerability allows local attackers to disclose sensitive information on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the IO80211Family kernel extension. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges in the context of the kernel. Apple macOS Catalina is a set of dedicated operating systems developed by Apple for Mac computers. A security vulnerability exists in the Wi-Fi component of Apple macOS Catalina versions prior to 10.15.3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2020-1-28-2 macOS Catalina 10.15.3, Security Update 2020-001 Mojave, Security Update 2020-001 High Sierra macOS Catalina 10.15.3, Security Update 2020-001 Mojave, and Security Update 2020-001 High Sierra are now available and address the following: AnnotationKit Available for: macOS Catalina 10.15.2 Impact: A remote attacker may be able to cause unexpected application termination or arbitrary code execution Description: An out-of-bounds read was addressed with improved input validation.

An out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Catalina 10.15.3, watchOS 6.1.2. A remote attacker may be able to cause unexpected application termination or arbitrary code execution. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple Messages. User interaction is required to exploit this vulnerability in that the target must open the Messages application.The specific flaw exists within the HandwritingProvider module in the Messages application. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Both Apple watchOS and Apple macOS Catalina are products of Apple Inc. in the United States. Apple macOS Catalina is a dedicated operating system developed for Mac computers. A buffer error vulnerability exists in the AnnotationKit component in Apple watchOS versions prior to 6.1.2 and macOS Catalina versions prior to 10.15.3.
