SuSE Security Announcement - proftpd

Sep 16, 1999, 20:45 (0 Talkback[s])

[ Via the suse-security-announce mailing list... ]

A security hole was discovered in the package mentioned above. Please update as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s).

Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue.

Please note, that that we provide this information on as "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package.


1. Problem Description

Several buffer overflows have been found in proftpd which have been verified to be exploitable from an remote attacker.

The fixing and finding of new holes is going on for over 2 weeks now, and there is no end in sight.

Even with all known fixes, proftpd is still vulnerable to remote vulnerablilities.

2. Impact

A remote attacker can gain root access to the system from remote.

3. Solution

Deactivate, or better, Deinstall the proftpd package.

proftpd will be dropped from current distributions until there can be put trust in this package.

We will provide an update, once a completely fixed version is out.

Until then, please use a secure ftpd server.
If you only need to provide readonly anonymous ftp access, we encourage you to get the anon-ftpd from Bernstein from ftp://koobera.math.uic.edu/www/anonftpd.html
Otherwise, we recommend to run the stock ftpd which comes by default with SuSE and is derived of OpenBSD.
