                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
http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS

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:

ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates

ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors listed at:

http://www.linux-mandrake.com/en/ftp.php3.

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.
