Subject: [RHSA-2002:036-26] Updated ethereal packages available
---------------------------------------------------------------------
Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated ethereal packages available
Advisory ID: RHSA-2002:036-26
Issue date: 2002-02-27
Updated on: 2002-09-12
Product: Red Hat Powertools
Keywords: ucd-snmp SNMP ethereal
Cross references: RHSA-2002:169 RHSA-2002:170
Obsoletes: RHSA-2000:116
CVE Names: CAN-2002-0012 CAN-2002-0013 CAN-2002-0353 CAN-2002-0401 CAN-2002-0402 CAN-2002-0403 CAN-2002-0404 CAN-2002-0821 CAN-2002-0822 CAN-2002-0834
---------------------------------------------------------------------
1. Topic:
Updated ethereal packages are available for Red Hat Powertools 6.2, 7, and
7.1. These packages are required for the Red Hat Security Advisory
regarding applications linked against the old ucd-snmp libraries and also
fix other security issues in ethereal.
2. Relevant releases/architectures:
Red Hat Powertools 6.2 - alpha, i386
Red Hat Powertools 7.0 - alpha, i386
Red Hat Powertools 7.1 - alpha, i386
3. Problem description:
Ethereal is a network traffic analyzer and monitor.
The Red Hat Security Advisory for ucd-snmp included updated libraries. All
applications linked against the old ucd-snmp libraries need to be
updated.
If you have updated your ucd-snmp package you must update the ethereal
package as well.
For all other third party applications possibly affected by the Red Hat
Security Advisory for ucd-snmp, please contact the software vendor.
This errata provides Ethereal version 0.9.6. Previous versions of Ethereal
were found to contain a number of security issues:
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 the BGP
dissector or the WCP dissector. (CAN-2002-0821)
Ethereal 0.9.4 and earlier allows remote attackers to cause a denial
of service and possibly excecute arbitrary code via the SOCKS,
RSVP, AFS, or LMP dissectors, which can be caused to core
dump. (CAN-2002-0822)
Due to improper string and error handling in Ethereal's ASN.1 parser, it
is possible for a malformed SNMP or LDAP packet to cause a memory
allocation or buffer overrun error in Ethereal versions before 0.9.2.
(CAN-2002-0013 CAN-2002-0012)
The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to
cause a denial of service (crash) via a certain malformed packet, which
causes Ethereal to allocate memory incorrectly, possibly due to zero-length
fields. (CAN-2002-0353)
The SMB dissector in Ethereal prior to version 0.9.2 allows remote
attackers to cause a denial of service (crash) or execute arbitrary code
via malformed packets that cause Ethereal to dereference a NULL pointer.
(CAN-2002-0401)
A buffer overflow in X11 dissector in Ethereal before 0.9.4 allows
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code while Ethereal is parsing keysyms. (CAN-2002-0402)
The DNS dissector in Ethereal before 0.9.4 allows remote attackers to
cause a denial of service (CPU consumption) via a malformed packet
that causes Ethereal to enter an infinite loop. (CAN-2002-0403)
A vulnerability in the GIOP dissector in Ethereal before 0.9.4 allows
remote attackers to cause a denial of service (memory consumption).
(CAN-2002-0404)
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.

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>
