1. Topic:

Updated ethereal packages are available which fix various security issues.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386

3. Problem description:

Ethereal is a package designed for monitoring network traffic on your
system.  Several security issues have been found in the Ethereal packages
distributed with Red Hat Linux 7.2 and 7.3.

A buffer overflow in Ethereal 0.9.5 and earlier allows remote attackers
to cause a denial of service or execute arbitrary code via the ISIS
dissector. (CAN-2002-0834)

Buffer overflows in Ethereal 0.9.4 and earlier allow remote attackers
to cause a denial of service or execute arbitrary code via (1) the BGP
dissector, or (2) the WCP dissector. (CAN-2002-0821)

Ethereal 0.9.4 and earlier allows remote attackers to cause a denial
of service and possibly execute arbitrary code via the (1) SOCKS, (2)
RSVP, (3) AFS, or (4) LMP dissectors, which can be caused to core
dump. (CAN-2002-0822)

Users of Ethereal should update to the errata packages containing Ethereal
version 0.9.6 which is not vulnerable to these issues.

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:


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):

68154 - ethereal 0.9.4 security issues
71099 - false dependency on gtk-1.2

6. RPMs required:

Red Hat Linux 7.2:




Red Hat Linux 7.3:

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:

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>
