Subject: CVE request - pyftpd insecure usage of temporary directory

Pyftpd creates log-file to a temporary directory using predictable
name. This allows a local attacker to create a denial of service
condition and discloses sensitive information to unprivileged users.
For example accounts of other users connecting to server and paths they

One should use tempfile.mkstemp
<> or
use /var/log/ -directory instead of /tmp/ and use proper file system
modes for the log-file.

This affects version: 0.8.4

Can I have CVE-identifier for this issue?
