Security update for pure-ftpd, pure-ftpd-debuginfo (important)

The OES Netware add-ons in pure-ftpd had a security problem
and some bugs, which are fixed by this update.

A local attacker could overwrite local files when the OES
remote server feature of pure-ftpd is enabled due to a
directory traversal. (CVE-2011-3171)

Additionally the following bugs have been fixed:

• bnc#699300 - FTP remote server navigation does not
  always succeed
• bnc#685447 - pure-ftpd does not throw an error when
  the name resolution fails during remote server navigation
• bnc#700335 - put files into NCP volumes fails
• bnc#703035 - remote_server feature opens a
  vulnerability with directory traversal & file overwriting
