It requires the target user (default: root) to execute 'crontab -e' or 'crontab /any/file' during the attack window.
Description
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.
