                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           xinetd
Date:                   June 11th, 2001
Advisory ID:            MDKSA-2001:055

Affected versions:      7.2, 8.0, Single Network Firewall 7.2
______________________________________________________________________

Problem Description:

 A bug exists in xinetd as shipped with Mandrake Linux 8.0 dealing with
 TCP connections with the WAIT state that prevents linuxconf-web from
 working properly.  As well, xinetd contains a security flaw in which
 it defaults to a umask of 0.  This means that applications using the
 xinetd umask that do not set permissions themselves (like SWAT, a web
 configuration tool for Samba), will create world writable files.  This
 update sets the default umask to 022.

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 Mandrake Linux 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
Mandrake Linux 8.0, look for it in "updates/8.0/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.
