CVE-2000-1096: crontab by Paul Vixie uses predictable file names for a temporary file and does not properly ensure that th...

Security readout for executives and security teams

This is an old Vixie cron crontab issue where unsafe temporary file handling could let a local user interfere while another user edits a crontab. The likely business impact is unauthorized scheduled command execution on affected legacy Unix-like systems. Public sources do not show active exploitation or a current vendor patch in the provided bundle. Exposure is most plausible on legacy systems running Paul Vixie/Vixie cron where crontab spool permissions allow local user writes. The source bundle does not identify affected distributions, package versions, or modern maintained forks. Treat this as a legacy local privilege and integrity risk, not an internet-scale emergency. Prioritize shared Unix servers, multi-user hosts, and older systems where local users may have shell access or weak spool permissions. Mitigation focus: Check operating-system or cron package vendor guidance for affected versions and fixes.; Ensure crontab spool directories are not writable by untrusted local users.; Upgrade or replace vulnerable Vixie cron packages where vendor advisories confirm exposure..
