paranoid option

Hi,

We have a program that decodes incoming email using ripmime and sends it
off to clamav for virus scanning. The decoding section looks like:

MIME_init();
LOGGER_set_output_mode(_LOGGER_STDERR);
MIME_set_uniquenames(1);
MIME_set_header_longsearch(1);
MIME_set_paranoid(1);
MIMEH_set_outputdir(q->tmpdir);
MIME_unpack(q->tmpdir, q->tmpfile, 0);
MIME_close();

Recently we saw an error in our clam daemon:

Mon Mar 8 03:01:07 2004 [15381] [critical] Could not untaint '全程心理卫生研究所（心理咨询）.doc'

Shouldn't MIME_set_paranoid(1) force 7 bit names? Also, is there a way
to just force naming of files to just say 1, 2, 3, ...? In this case, we
don't care at all about the name, just want it extracted.

Cheers,

Alex

No way of obtaining that mailpack is there? Looks like the filename was generated by not passed to the FNFILTER module.

Is the error from the clam daemon about the filename, or about the contents?

I haven't got anything like that yet, it could be possible to do - though it would require another change to the source
code.

Regards.

Not for that one unfortunately. We've modified the daemon so if it sees
an invalid name again, it will save the original message.

It's about the filename.

Would you be interested in a patch that does this? If so, any tips on
how you would want it implemented?

Cheers,

Alex

Here's a reproducable case. Grab this piece of spam at:

http://www.gossamer-threads.com/ripmime.txt

and then:

[alex [at] gossame tmp]$ ./ripmime-1.3.1.0/ripmime -i ripmime.txt -d foo/ --paranoid
[alex [at] gossame tmp]$ ls foo/
textfile0 textfile1 软件源码清单.txt
[alex [at] gossame tmp]$

Cheers,

Alex
