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
  exploitation.

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 from OpenBSD.
