SuSE Security Announcement
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.

SuSE Security Announcement
Package: cron-3.0.1-75 (Vixie Cron) and previous versions
Date: Fri Aug 27 17:56:48 CEST 1999
Affected: maybe all Unix operatingsystems using crond
______________________________________________________________________________
Some security holes were 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
Three security threats were found in the vixie crond, which is shipped
with SuSE Linux.
1) no boundchecking on a local buffer, while copying data from MAILTO
2) passing invalid options to sendmail
3) it doesn't drop root privileges while sending acknowledge mail
to a user
2. Impact
1) local root compromise by putting arbitrary code on the stack
2/3) triggering a local denial-of-service attack by starting alot
of sendmail daemons
execute sendmail with options that only root could apply
(like '-C'), which also leads to local root compromise
3. Solution
Updated the crond package from our FTP server.
