"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 :

  - FTP remote server navigation does not always succeed.
    (bnc#699300)

  - pure-ftpd does not throw an error when the name
    resolution fails during remote server navigation.
    (bnc#685447)

  - put files into NCP volumes fails. (bnc#700335)

  - remote_server feature opens a vulnerability with
    directory traversal & file overwriting. (bnc#703035)"
