| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Vixie Cron versions prior to 3.0pl1-133
Description
The issue is related to a memory allocation problem in the cron daemon, allowing an attacker to cause a denial of service by consuming excessive memory. This can be achieved by creating a large crontab file, as the system accepts an unlimited number of lines.
Recommendations
For Vixie Cron versions prior to 3.0pl1-133, update to the 3.0pl1-133 Debian package or later to resolve the issue. As a temporary workaround, consider restricting access to the crontab file to prevent malicious modifications.
