This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system.\n\n * CVE-2023-43786: A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.\n\n * CVE-2023-43787: A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.",
