                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
If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

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

You can download the updates directly from:

Or try one of the other mirrors listed at:


Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/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, so if you want an immediate upgrade, please use one of the two above-listed mirrors.
