Package: proftpd-1.2.0pre6 and earlier
Date: Thu Sep 16 20:59:18 CEST 1999
Affected: all UNIX platforms using proftpd
______________________________________________________________________________
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.
