| Type: | Security Advisory |
| Severity: | N/A |
| Issued on: | 2002-05-17 |
| Last updated on: | 2002-10-04 |
| Affected Products: | Red Hat Linux 6.2 Red Hat Linux 7.0 Red Hat Linux 7.1 Red Hat Linux 7.2 |
| CVEs (cve.mitre.org): |
CVE-2002-0380 |
Details
Updated tcpdump, libpcap, and arpwatch packages are available for Red
Hat Linux 6.2 and 7.x. These updates close a buffer overflow when handling
NFS packets.
[Update 3 October 2002]
Replacement packages have been added for Red Hat Linux 6.2 as the previous
packages could not be installed with the version of RPM that shipped with
Red Hat Linux 6.2. Replacement packages have also been added for Red Hat
Linux 7.0 as the previous packages were not built correctly.
tcpdump is a command-line tool for monitoring network traffic. Versions of
tcpdump up to and including 3.6.2 have a buffer overflow that can be
triggered when tracing the network by a bad NFS packet.
We are not yet aware if this issue is fully exploitable; however, users of
tcpdump are advised to upgrade to these errata packages which contain a
patch for this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0380 to this issue. This issue was found by
David Woodhouse of Red Hat.
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.
