Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated ethereal packages are available
Advisory ID: RHSA-2002:169-13
Issue date: 2002-08-02
Updated on: 2002-08-28
Product: Red Hat Linux
Keywords: ethereal RSVP AFS LMP dissector WCP BGP
Cross references: RHSA-2002:170

CVE Names: CAN-2002-0834 CAN-2002-0821 CAN-2002-0822
---------------------------------------------------------------------
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:
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):
