3. Problem description:

The xloadimage utility displays images in an X Window System window,
loads images into the root window, or writes images into a file.
Xloadimage supports many image types (including GIF, TIFF, JPEG, XPM,
and XBM).

A flaw was discovered in xloadimage where filenames were not properly
quoted when calling the gunzip command.  An attacker could create a file
with a carefully crafted filename so that it would execute arbitrary
commands if opened by a victim.  The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2005-0638 to
this issue.

Another bug in xloadimage would cause it to crash if called with certain
invalid TIFF, PNM, PBM, or PPM file names.

All users of xloadimage should upgrade to this erratum package which
contains backported patches to correct these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

5. Bug IDs fixed (http://bugzilla.redhat.com/):

70867 - xloadimage crashes with some TIFF images
78481 - bad source code
150700 - CAN-2005-0638 xloadimage multiple issues.
