VAR-202109-1334
Vulnerability from variot - Updated: 2023-12-18 11:18A 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
