Description

The remote NewStart CGSL host, running version MAIN 7.02, has libX11 packages installed that are affected by multiple vulnerabilities:

This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system. (CVE-2023-43785)

- 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.
