The following products and versions are affected: macOS: 10.15 19A583, 10.15 19A602, 10.15 19A603, 10.15.1 19B88, 10.15.2 19C57, 10.15.3 19D76, 10.15.4 19E266, 10.15.4, 19E287, 10.19.5 5 19F101, 10.15.6 19G73, 10.15.6 19G2021, 10.15.7 19H2, 10.15.7 19H4, 10.15.7

A local user may be able to cause unexpected system termination or read kernel memory. This issue is fixed in macOS Big Sur 11.4, Security Update 2021-003 Catalina. An out-of-bounds read issue was addressed by removing the vulnerable code. 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 handling of IOCTL 0x20006 in the AppleIntelKBLGraphics kext. 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 escalate privileges and execute code in the context of the kernel. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. A buffer error vulnerability exists in macOS Big Sur due to the fact that a local user can run a specially crafted program to trigger an out-of-bounds read error and read the contents of kernel memory on the system. Affected versions: macOS: 11.0 20A2411, 11.0.1 20B29, 11.0.1 20B50, 11.1 20C69, 11.2 20D64, 11.2.1 20D74, 11.2.1 20D75, 11.2.2 20D80, 11.2.3 20D91, 1E2.3, 20D91, 11.2.3, 20D74 20E241

This issue was addressed with improved checks. This issue is fixed in macOS Big Sur 11.4. A non-privileged user may be able to modify restricted settings. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. An access control bug exists in macOS Big Sur that stems from allowing local users to gain unauthorized access to otherwise restricted functionality. Affected versions: macOS: 11.0 20A2411, 11.0.1 20B29, 11.0.1 20B50, 11.1 20C69, 11.2 20D64, 11.2.1 20D74, 11.2.1 20D75, 11.2.2 20D80, 11.2.3 20D91, 1E2.3, 20D91, 11.2.3, 20D74 20E241

This issue was addressed with improved checks. This issue is fixed in iOS 14.7, macOS Big Sur 11.5, watchOS 7.6, tvOS 14.7, Security Update 2021-005 Mojave, Security Update 2021-004 Catalina. A local attacker may be able to cause unexpected application termination or arbitrary code execution. plural Apple There are unspecified vulnerabilities in the product.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Pillow is a Python-based image processing library.

This issue was addressed with improved checks. This issue is fixed in tvOS 14.6, Security Update 2021-004 Mojave, iOS 14.6 and iPadOS 14.6, Security Update 2021-003 Catalina, macOS Big Sur 11.4, watchOS 7.5. A local attacker may be able to elevate their privileges. This vulnerability allows local attackers to escalate privileges 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 CVMServer daemon. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Apple tvOS is a smart TV operating system developed by Apple (Apple).
