[9.01a x86] TC adds garbage to decoded EML attachments

[MVV]

Please try extracting the attached u8text.txt file using TC's decode function and by opening this EML with a mail client:

Code: Select all

Subject: decode bug
MIME-Version: 1.0
Content-Type: multipart/mixed;
 boundary="----------0C41AE0413CB31237"

------------0C41AE0413CB31237
Content-Type: multipart/alternative;

While email client extracts the file properly, TC adds extra garbage bytes to it. Pure file size is 102 bytes.

Please try with TC 9.10 beta. TC 9.0a does NOT support nested sections (sections within sections) in MIME encoded files. TC 9.10 now supports them.

[MVV]

Unfortunately it still doesn't work with TC 9.10b1 with this sample EML.

[ghisler(Author)]

I can confirm the problem, it's happening due to an unusual triple nested sections. I will try to support that too.

[MVV]

Thanks!
As I see it, you can unpack it layer by layer, with respect to each multipart's boundary, it shouldn't be too hard...

[ghisler(Author)]

This should be fixed in TC 9.10 beta 2, please test it!

[MVV]

Works fine in 9.10b2, thank you!

[ghisler(Author)]

Great, thanks! Please let me know if you find a file where it doesn't work correctly.

Hi,

I have an email with a jpg attachment. I saved it in eml format and when I decode it with TC I get 2 files. One is the text of the mail, it's OK.
The other one gets decoded to a file named as the original jpg but the content is not jpg format but base64 I suppose. It is a plain copy from the eml but if I rename it to have b64 extension and decode it with TC I get a "WARNING: nothing decoded!" message. Is this a bug of TC or an error in the eml file? The link to the eml file (zipped) is here.

w w w kotiposti dot net slash lkelemen slash jesse dot zip

I can not put it here as an URL as I'm new here.
I use TC 9.12 64bit

Thanks
Lajos
