    Linux Advisory Watch is a comprehensive newsletter that outlines the
    security vulnerabilities that have been announced throughout the week.It
    includes pointers to updated packages and descriptions of each
    This week, advisories were released for pine, rsync, FreeBSD kernel, wmtv,
    and telnet.  The vendors include Conectiva, Debian, FreeBSD, and Red Hat.
    Also this week, LinuxSecurity.com has released the latest version of the

    LinuxSecurity.com Feature: Approaches to choosing the strength of your
    security measures - Anton Chuvakin discusses the known approaches to
    choosing the level of security for your organization, risk assessment, and
    finding the balance between effective security practices and the existing
    Why be vulnerable? Its your choice. - Are you looking for a solution that
    provides the applications necessary to easily create thousands of virtual
    Web sites, manage e-mail, DNS, firewalling database functions for an
    entire organization, and supports high-speed broadband connections all

    features and more!
    |  pine                           | ----------------------------//
    A vulnerability[2] in the pine URL handler was discovered that allows
    remote attackers to execute arbitrary shell commands in the user's machine
    by encapsulating them in a URL using environment variables. This
    vulnerability only affects users whith the msg-view-url option enabled
    (which is not the default).
     Conectiva Vendor Advisory: 
    |  rsync                          | ----------------------------//
    In Debian Security Advisory DSA-106-1 we reported a exploitable problem in
    rsync. For details please see that advisory. Unfortunately the patch used
    to fix that problem broke rsync.  This has been fixed in version 2.3.2-1.5
    and we recommend you upgrade to that version immediately.

     Debian Vendor Advisory: 
    |  FreeBSD Kernel                 | ----------------------------//
    On vulnerable FreeBSD systems where procfs is mounted, unprivileged local
    users may be able to cause a kernel panic. A race condition existed where
    a file could be removed between calling fstatfs() and the point where the
    file is accessed causing the file descriptor to become invalid.  This may
    allow unprivileged local users to cause a kernel panic.  Currently only
    the procfs filesystem is known to be vulnerable.

     FreeBSD Vendor Advisory: 
    |  wmtv                           | ----------------------------//
    Nicolas Boullis found some security problems in the wmtv package (a
    dockable video4linux TV player for windowmaker) which is distributed in
    Debian GNU/Linux 2.2.  With the current version of wmtv, the configuration
    file is written back as the superuser, and without any further checks.  A
    mailicious user might use that to damage important files.

     MD5 checksum: 270d8553f9d732d612154dd0927ceece 
     Debian Vendor Advisory: 
    |  telnet                         | ----------------------------//
    New telnet, telnet-server packages are available for Red Hat Linux 5.2,
    5.2, 7.0 and 7.1. These packages fix a problem where buffer overflows can
    provide root access to local users. It is recommended that all users
    update to the fixed packages.
