                Linux-Mandrake Security Update Advisory

Package name:           proftpd
Date:                   February 8th, 2001
Advisory ID:            MDKSA-2001:021

Affected versions:      7.2

Problem Description:

The ProFTPD FTP server has problems with memory leaking that could be used in a DoS attack, as reported by Wojciech Purczynski. A memory leak will happen every time a SIZE command was given provided that the scoreboard file is not writable, which is not the case in a default Linux-Mandrake installation. A similar problem also existed with the USER command where every time it was given the server would use more memory. Additionally, some format string vulnerabilities were reported by Przemyslaw Frasunek which have also been fixed.

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.

Linux-Mandrake 7.2:
a2e330bd49855d74bfbb2f1e80c3e312 7.2/RPMS/proftpd-1.2.0rc3-1.1mdk.i586.rpm
3ec2a5ee6b834e1193de5e3b738eaa53 7.2/SRPMS/proftpd-1.2.0rc3-1.1mdk.src.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 -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.
