1. Topic:
Updated Ethereal packages that fix a number of exploitable security issues
are now available.
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 program for monitoring network traffic.
A number of security issues affect Ethereal. By exploiting these issues,
it may be possible to make Ethereal crash or run arbitrary code by
injecting a purposefully-malformed packet onto the wire or by convincing
someone to read a malformed packet trace file.
A buffer overflow in Ethereal 0.9.15 and earlier allows remote attackers
to cause a denial of service and possibly execute arbitrary code via a
malformed GTP MSISDN string. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2003-0925 to
this issue.
Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of
service (crash) via certain malformed ISAKMP or MEGACO packets. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0926 to this issue.
A heap-based buffer overflow in Ethereal 0.9.15 and earlier allows
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code via the SOCKS dissector. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0927
to this issue.
Users of Ethereal should update to these erratum packages containing
Ethereal version 0.9.16, 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.
Please note that this update is available via Red Hat Network. 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.
