The vulnerability CVE-2022-32810

This vulnerability allows an app to bypass file permissions, read or write data from other apps, and access data from other apps. There are two ways in which this issue can occur: the first is by exploiting a memory handling flaw and the second is by exploiting the sharing handling flaw. The memory handling flaw occurs when an app does not check a parameter before writing to a buffer. On Windows platforms, this would mean that when an app handles a maliciously crafted image that was passed in as a parameter of a function call, it may be able to write to arbitrary memory locations without being detected. The sharing handler flaw occurs when an app uses insecure file operations on behalf of another app. An app could exploit this issue by mounting exfiltration attacks through remote procedures calls (RPC) or opening files located on removable media. This issue would be fixed with improved file permissions checking and increased authentication on RPC requests.
