Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name: rp-pppoe
Date: December 18th, 2000
Advisory ID: MDKSA-2000:084

Affected versions: 7.1, 7.2
________________________________________________________________________

Problem Description:

rp-pppoe is a userspace PPPoE client mainly used with ADSL connections
which require PPP. Versions prior to 2.5 have a security problem that,
when exploited, causes the connection to be dropped. If rp-pppoe
receives a crafted TCP segment with an option where the option-length
field is zero (illegal), the program would enter an infinite loop and
the connection would time-out and be dropped. This is only possible
if the user uses the "Clamp MSS" option.
________________________________________________________________________

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 Linux-Mandrake 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.

Linux-Mandrake 7.1:
589bdccafbf374244ea2e940ae6df7ba 7.1/RPMS/rp-pppoe-2.5-2.1mdk.i586.rpm
e07be9faefcf1a58df48e872c9c7c068 7.1/SRPMS/rp-pppoe-2.5-2.1mdk.src.rpm

Linux-Mandrake 7.2:
d64a2bff24c05941624865facbc3ac8e 7.2/RPMS/rp-pppoe-2.5-2.2mdk.i586.rpm

________________________________________________________________________

To upgrade automatically, use MandrakeUpdate.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and uprade 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
Linux-Mandrake 7.2, look for it in "updates/7.2/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.
