                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: tcpdump
    Date: June 13th, 2001
    Advisory ID: MDKSA-2001:056

    Affected versions: 7.1, 7.2, 8.0, Corporate Server 1.0.1,
                            Single Network Firewall 7.2
    ________________________________________________________________________

    Problem Description:

     A number of remote buffer overflows were discovered in the tcpdump
     package that would allow a remote attack of the local tcpdump process.
     Intrusion detection using tcpdump would no longer be useful due to the
     attack stoping all network activity on the system. As well, this new
     version of tcpdump fixes the vulnerability with decoding AFS ACL
     packets which would allow a remote attacker to run arbitrary code on
     the local system with root privilege.

    Please verify the update prior to upgrading to ensure the integrity of
    the downloaded package. You can do this with the command:
      rpm --checksig package.rpm
    You can get the GPG public key of the Mandrake Linux Security Team at
      http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
    If you use MandrakeUpdate, the verification of md5 checksum and GPG
    signature is performed automatically for you.

    To upgrade automatically, use MandrakeUpdate.

    If you want to upgrade manually, download the updated package from one
    of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".

    You can download the updates directly from one of the mirror sites
    listed at:

      http://www.linux-mandrake.com/en/ftp.php3.

    Updated packages are available in the "updates/[ver]/RPMS/" directory.
    For example, if you are looking for an updated RPM package for
    Mandrake Linux 8.0, look for it in "updates/8.0/RPMS/". Updated source
    RPMs are available as well, but you generally do not need to download
    them.

    Please be aware that sometimes it takes the mirrors a few hours to
    update.
