    Synopsis: Updated rsync package fixes security issues
    Advisory ID: FLSA:2003
    Issue date: 2004-09-30
    Product: Red Hat Linux
    Keywords: Bugfix
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2003
    CVE Names: CAN-2004-0426 CAN-2004-0792

    1. Topic:

    An updated rsync package that fixes several security issues is now
    available.

    The rsync program synchronizes files over a network.

    2. Relevent releases/architectures:

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

    3. Problem description:

    Rsync before 2.6.1 does not properly sanitize paths when running a
    read/write daemon without using chroot. This could allow a remote
    attacker
    to write files outside of the module's "path", depending on the
    privileges
    assigned to the rsync daemon. Users not running an rsync daemon, running
    a
    read-only daemon, or running a chrooted daemon are not affected by this
    issue. The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CAN-2004-0426 to this issue.

    Versions of rsync up to and including version 2.6.2 contain a path
    sanitization issue. This issue could allow an attacker to read or write
    files outside of the rsync directory. This vulnerability is only
    exploitable when an rsync server is enabled and is not running within a
    chroot. The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CAN-2004-0792 to this issue.

    Users of rsync are advised to upgrade to this updated package, which
    contains backported patches and is not affected by 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.
