                Linux-Mandrake Security Update Advisory

Package name:           vixie-cron
Date:                   February 20th, 2001
Advisory ID:            MDKSA-2001:022

Affected versions:      6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1

Problem Description:

A buffer overflow exists in the 'crontab' command if it was called by a user with a username longer than 20 characters. If the system administrator has created usernames of that length, it would be possible for those users to gain elevated privileges.

Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command:
rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

To upgrade automatically, use <<MandrakeUpdate>>.

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and uprade with "rpm -Uvh package_name".

You can download the updates directly from:

Or try one of the other mirrors listed at:


Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.

Please be aware that sometimes it takes the mirrors a few hours to update, so if you want an immediate upgrade, please use one of the two above-listed mirrors.
