Red Hat Security Advisory
Synopsis: Updated ethereal packages fix security vulnerabilities
Advisory ID: RHSA-2003:076-01
Issue date: 2003-04-23
Updated on: 2003-04-23
Product: Red Hat Linux
Keywords:
Cross references:
Obsoletes: RHSA-2002:290
CVE Names: CAN-2003-0081 CAN-2003-0159
---------------------------------------------------------------------
1. Topic:
Updated ethereal packages are now available which fix a format string
bug and a heap-based buffer overflow.
2. Relevant releases/architectures:
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386
3. Problem description:
Ethereal is a package designed for monitoring network traffic on your
system.
Ethereal 0.9.9 and earlier allows remote attackers to cause a denial
of service (crash) and possibly execute arbitrary code via carefully
crafted SOCKS packets. Red Hat would like to thank Georgi Guninski for
reporting this issue.
Additionally, a heap-based buffer overflow in the NTLMSSP code for Ethereal
0.9.9 and earlier allows remote attackers to cause a denial of service and
possibly execute arbitrary code.
Users of Ethereal should update to the erratum packages containing Ethereal
version 0.9.11 which are 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.

These packages are GPG signed by Red Hat for security. Our key is
available at http://www.redhat.com/solutions/security/news/publickey/
You can verify each package with the following command:
rpm --checksig -v <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:
md5sum <filename>
