[RHBA-2002:080-09] Malformed header can crash evolution



---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Bug Fix Advisory

Synopsis:          Malformed header can crash evolution
Advisory ID:       RHBA-2002:080-09
Issue date:        2002-05-06
Updated on:        2002-05-09
Product:           Red Hat Linux
Keywords:          evolution
Cross references:  
Obsoletes:         
---------------------------------------------------------------------

1. Topic:

Updated packages are available for Evolution which fix a vulnerability in
the mime parsing component.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386

3. Problem description:

Evolution is a personal/workgroup information management application for
Linux and UNIX.

There is a vulnerability in Evolution's mime parsing code which could end
up in an infinite loop if it is sent a mail with properly malformed
headers.  This causes evolution's memory usage to increase until it crashes.

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.redhat.com/bugzilla for more info):



6. RPMs required:

Red Hat Linux 7.3:

SRPMS:
ftp://updates.redhat.com/7.3/en/os/SRPMS/evolution-1.0.3-6.src.rpm

i386:
ftp://updates.redhat.com/7.3/en/os/i386/evolution-1.0.3-6.i386.rpm



7. Verification:

MD5 sum                          Package Name
--------------------------------------------------------------------------
79d785653aed69679032d9bdf60f01c6 7.3/en/os/SRPMS/evolution-1.0.3-6.src.rpm

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:
    http://www.redhat.com/about/contact/pgpkey.html

You can verify each package with the following command:
    rpm --checksig  <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg <filename>
