                Linux-Mandrake Security Update Advisory
_________________________________________________________________________

Package name:           wu-ftpd
Advisory Date:          January 15th, 2001
Original Advisory Date: January 10th, 2001
Advisory ID:            MDKSA-2001:001-1

Affected versions:      6.0, 6.1, 7.0, 7.1, 7.2

Problem Description:

 WireX discovered a temporary file creation bug in the 2.6.1 release of
 wu-ftpd.  The problem exists in the privatepw helper program.  As well,
 Linux-Mandrake 7.2 users must update to this package as it fixes
 security problems as discussed in the prior advisory, MDKSA-2000:014,
 which had not been previously addressed for 7.2.

Update:

 All of the updated packages for Linux Mandrake versions 6.0 through 7.1
 and the packages for Corporate Server 1.0.1 had an incorrect dependency
 on the xinetd package which prevented MandrakeUpdate from installing
 the updates.  Updated packages for these versions have been released
 that are no longer dependant upon xinetd.

 All of the updated packages for Linux Mandrake versions 6.0 through 7.1
 and the packages for Corporate Server 1.0.1 installed the wrong pam
 support file which prevented anyone from logging into the FTP server.

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.
