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)
