Fedora Legacy Advisories: tcpdump, cadaver

Sep 30, 2004, 20:28 (0 Talkback[s])

Fedora Legacy Update Advisory

Synopsis: Updated tcpdump resolves security vulnerabilities
Advisory ID: FLSA:1468
Issue date: 2004-09-29
Product: Red Hat Linux
Keywords: Security
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=3D1468
CVE Names: CAN-2004-0183, CAN-2004-0184



1. Topic:

Updated tcpdump packages that fix multiple security vulnerabilities are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

Tcpdump is a command-line tool for monitoring network traffic.

Tcpdump v3.8.1 and earlier versions contained multiple flaws in the packet display functions for the ISAKMP protocol. Upon receiving specially crafted ISAKMP packets, tcpdump would try to read beyond the end of the packet capture buffer and subsequently crash.

All users are advised to upgrade to these updated packages, which contain a backported fix and are not vulnerable to this issue.

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 yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs/ for directions on how to configure yum and apt-get.

These packages are GPG signed by Fedora Legacy for security. Our key is available from http://www.fedoralegacy org/about/security.php

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 sha1sum with the following command:

sha1sum <filename>

Fedora Legacy Update Advisory

Synopsis: Updated cadaver resolves security vulnerabilities
Advisory ID: FLSA:1552
Issue date: 2004-09-29
Product: Red Hat Linux
Keywords: Security
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=3D1552
CVE Names: CAN-2004-0179, CAN-2004-0398



1. Topic:

Updated cadaver packages that fix multiple security vulnerability are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

3. Problem description:

An updated cadaver package that fixes a vulnerability in neon exploitable by a malicious DAV server is now available.

cadaver is a command-line WebDAV client that uses inbuilt code from neon, an HTTP and WebDAV client library.

Versions of the neon client library up to and including 0.24.4 have been found to contain a number of format string bugs. An attacker could create a malicious WebDAV server in such a way as to allow arbitrary code execution on the client should a user connect to it using cadaver. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0179 to this issue. This issue was addressed in a previous update for Red Hat Linux 9.

Stefan Esser discovered a flaw in the neon library which allows a heap buffer overflow in a date parsing routine. An attacker could create a malicious WebDAV server in such a way as to allow arbitrary code execution on the client should a user connect to it using cadaver. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0398 to this issue.

Users of cadaver are advised to upgrade to this updated package, which contains patches correcting 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.
