NeXT 1.0a and 1.0 is a Unix operating system that allows local users to gain privileges via a combination of the npd program and weak directory permissions. This vulnerability could potentially lead to unauthorized access to sensitive data or system configuration.
You're affected if you use NeXT 1.0a or 1.0 with publicly accessible printers. To check, run npd -l on your system (this command may not be available in all versions).
Note: This is a niche software, and if you don't recognize the name, you're probably not affected.
Version info: Not specified in the advisory.
