    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=1552
    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. 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>
