VAR-202006-1644
Vulnerability from variot - Updated: 2024-02-13 22:29This issue was addressed with improved checks. This issue is fixed in macOS Catalina 10.15.5. An application may be able to gain elevated 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 handling of Core Virtual Machine Service caches. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel. Apple macOS Catalina is a set of dedicated operating systems developed by Apple for Mac computers. CVMS is one of the core virtual machine server components. An attacker could exploit this vulnerability to elevate privileges
