Package : cron
Version : 3.0pl1-128+deb9u2
CVE ID : CVE-2017-9525 CVE-2019-9704 CVE-2019-9705 CVE-2019-9706
Debian Bug : 809167
Brief introduction
CVE-2017-9525
Fix group crontab to root escalation via postinst.
CVE-2019-9704
A very large crontab created by a user could crash the daemon.
CVE-2019-9705
Enforce maximum crontab line count of 10000 to prevent a malicious
user from creating an excessivly large crontab.
CVE-2019-9706
Fix for possible DoS by use-after-free.
Additionally, a bypass of /etc/cron.{allow,deny} on failure to open has
been fixed. If these files exist, then they must be readable by the user
executing crontab(1). Users will now be denied by default if they aren't.
For Debian 9 stretch, these problems have been fixed in version
3.0pl1-128+deb9u2.
We recommend that you upgrade your cron packages.
