Hello,

I installed fudforum to tend replace some phpbb install, i made some corrections in convert script (i upload if works well) but i have a big problem: msg file. The msg file is file based (maybe insecure) and probably have some other filesystem based weekness (not closed properly, not synced, or simply corrupted, at not last over quota problem or full disk problem. In $subject situation what's happening? Very bad if the file zeroed or chunked.

Thanks,

If you are worried about msg file, be more concerned about all your configuration files that contain passwords they suffer from the same insecurities.

Does not make sense, please clarify.

The forum does strict validation checks to ensure data was properly written to that file.

Clarify:

Disk is near full, forums open msg file to write, while writing disk is full. What's happen msg file filled to disk full state and chunked data remainig or reset pervious state?
Theoreticaly possible chunk message file or zeroing(rewrite) under some filesystem situation?

When the forum writes the message it checks if it has been written, by comparing the length of the message to the # of bytes written. If two are not the same an error will be generated indicating disk space limit has been reached.
