Since Update 9, users who upload files via vsftpd service have been reporting
unusal permissions-based problems.  Situation has been going on since U9, but
all affected users happened to be using the same FTP client (Transmit on Mac) so
I had put it down to that.  It wasn't until today that I tested the situation
myself using lftp, and I can confirm unusual permissions behaviour with the U9
release of vsftpd.

Version-Release number of selected component:

  vsftpd-1.2.1-3E.12

Not affected:

  vsftpd-1.2.1-3E.6

Steps to reproduce:

1. I take a file with 644 permissions.

  -rw-r--r--  1 cpaul users  3380 Jul 12  2006 TEXTFILE

2. Upload it

  lftp cpaul:/> put TEXTFILE
  
3. Check the remote listing

  lftp cpaul:/> ls -la
  ----rw-r-x    1 501 501  3380 Jul 11 06:27 TEXTFILE

4. Downgrade vsftpd to vsftpd-1.2.1-3E.6 and repeat

  lftp cpaul:/> put TEXTFILE
  lftp cpaul:/> ls -la
  -rw-r--r--    1 501 501  3380 Jul 11 06:28 REFACTOR

The only local config in my vsftpd.conf is listed below:
