Unixware Cron Command Line Buffer Overflow Vulnerability

by platon on July 1st, 2001
Cron is a task scheduler for Unix systems.

Crontab is prone to a buffer overflow in handling of command line parameters. An attacker may take advantage of this by executing crontab with a malicious argument.

If successfully exploited, this vulnerability will surrender 'root' access to the remote attacker.

The vendor has supplied a fix for this issue. It can be installed with the following commands:

# uncompress /tmp/erg711714a.Z

# pkgadd -d /tmp/erg711714a
