DESCRIPTION
A memory corruption issue was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave. Processing a maliciously crafted image may lead to arbitrary code execution. macOS Big Sur Exists in an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the CoreGraphics framework. 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. Apple macOS could allow a remote malicious user to execute arbitrary code on the system, caused by a memory corruption in the ImageIO component. By persuading a victim to open a specially crafted image file, an attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
