CVE-2000-1096: Paul Vixie Vixie Cron

Low severity, CVSS 3.7. EPSS: 0.8% chance of exploitation in the next 30 days.

crontab by Paul Vixie uses predictable file names for a temporary file and does not properly ensure that the file is owned by the user executing the crontab -e command, which allows local users with write access to the crontab spool directory to execute arbitrary commands by creating world-writeable temporary files and modifying them while the victim is editing the file.
