Posted by LinuxSecurity.com Team   
RedHat Linux Updated imlib packages are now available for Red Hat Linux 6.2, 7,7.1 and 7.2 which fix potential problems loading untrusted images.

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          New imlib packages available
Advisory ID:       RHSA-2002:048-06
Issue date:        2002-03-15
Updated on:        2002-03-20
Product:           Red Hat Linux
Keywords:          
Cross references:  
Obsoletes:         
---------------------------------------------------------------------

1. Topic:

Updated imlib packages are now available for Red Hat Linux 6.2, 7,
7.1 and 7.2 which fix potential problems loading untrusted images.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

3. Problem description:

Imlib versions prior to 1.9.13 would fall back to loading images
via the NetPBM package, which has various problems that make it
unsuitable for loading untrusted images. Imlib 1.9.13 also fixes
various problems in arguments passed to malloc().

These problems may allow attackers to construct images that,
when loaded by a viewer using Imlib, could cause crashes 
or potentially the execution of arbitrary code.

Users are advised to upgrade to these errata packages, which
contain Imlib 1.9.13.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (http://bugzilla.Red Hat.com/bugzilla for more info):
