                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.
