CVE-2023-24040 : What You Need to Know

This CVE record pertains to a vulnerability identified as "dtprintinfo" in the Common Desktop Environment 1.6. The bug lies in the parser of lpstat, an external command invoked during the listing of available printer names. This flaw allows low-privileged local users to inject arbitrary printer names via the $HOME/.printers file, enabling them to manipulate control flow and access memory contents on Solaris 10 systems. It's important to note that this vulnerability affects only products that are no longer supported by the maintainer.
