                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           xli/xloadimage
Date:                   September 12th, 2001
Original Advisory Date: August 31st, 2001
Advisory ID:            MDKSA-2001:073-1

Affected versions:      7.1, 7.2, 8.0, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

 A buffer overflow exists in xli due to missing boundary checks.  This
 could be triggered by an external attacker to execute commands on the
 victim's machine.  An exploit is publically available.  xli is an image
 viewer that is used by Netscape's plugger to display TIFF, PNG, and
 Sun-Raster images.

Update:

 The xloadimage package uses the same code as xli and is likewise
 vulnerable.  An update is provided for xloadimage which was only
 provided with Linux-Mandrake 7.2.

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.
