                Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name:           ntp/xntp3
Date:                   April 6th, 2001
Advisory ID:            MDKSA-2001:036

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

Problem Description:

 Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> reported that ntp 
 daemons such as ntp and xntp3 are vulnerable to a buffer overflow that
 can lead to a remote root exploit.  Linux-Mandrake users are urged to
 upgrade ntp and xntp3 immediately.
________________________________________________________________________

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 upgrade with "rpm -Fvh *.rpm".  

You can download the updates directly from one of the mirror sites
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 7.2, look for it in "updates/7.2/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.
