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
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 7.2:
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 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
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.
