The munpack utility which is part of the mpack package does not handle
attachment filenames that are split into parts. The attached patch fixes this.

I have tested the patched version against a variety of split filenames formats,

some mail senders add a ; to the end of each part, some don't. And it
have worked
fine for all the mails that I've tested it against so far.

I have attached the patch as a file since Gmail is known to mess up
inlined patches.

Hi,

We’ve the same problem with munpack so I was happy to see your patch. I downloaded the sources with

dget  http://deb.debian.org/debian/pool/main/m/mpack/mpack_1.6-18.dsc

applied your patch to the sources and a build it without problems.

I tested it with a message which has this multiline filename and it worked good except, that the filename has an additional X at the place where a new line starts.

In exact, the mime Header says

Content-Disposition: attachment;
        filename*0=Report_source01_destcustomer_report_data_2024.06.09_08.30.xl;
        filename*1=s

and the patched munpack saves the file as

Report_source01_destcustomer_report_data_2024.06.09_08.30.xlXs (application/vnd.ms-excel)

I’m not quite sure where this X comes from and sadly, my C knowledge isn’t good enough. Do you’ve any idea what is causing this X?

Thanks! a lot
Chris
