JPG and JPEG attachments do not show up within messages from some providers

[gianlucagiacometti]

Prerequisites

• I have searched for duplicate or closed issues
• I can recreate the issue with all plugins disabled

Describe the issue

When I receive messages with attached .jpeg or .jpg files from some providers (Exchange and Gmail included), I see the clip in the message list but no attachment shows up either in the message preview or in the message if I double-click it.
If I forward to myself from my phone with Aquamail, it shows correctly.

This issue does not happen if I receive other type of attachments (.png, .pdf).

I have the latest roundcube git version updated today and I tried in all my 3 servers (with the same php8.3).

I checked the source and the attachment is there:

--0000000000003977590625b291eb
Content-Type: image/jpeg; 
	name="nice_pic.jpeg"
Content-Disposition: attachment; 
	filename="nice_pic.jpeg"
Content-Transfer-Encoding: base64
Content-ID: <f_m2vz2apx0>
X-Attachment-Id: f_m2vz2apx0

and goes on with encoded jpeg

What browser(s) are you seeing the problem on?

Chrome, Edge, Firefox, Other

What version of PHP are you using?

v8.3

What version of Roundcube are you using?

1.7-git

JavaScript errors

no errors in the console

PHP errors

no errors in log file

Hi Alec,
I can provide any information that you think can be useful.
Maybe I can send you the full source of one message with the problem.
I attach two screenshot to show the issue (coming from a gmail account).
That also happens with all plugins disabled.

Thank you in advance

I also tried with my phone and duckduckgo browser. Same problem.

This might be related to or the same as #9565. Can you check if this behaviour exists with Roundcubemail v1.6.9, too?

[gianlucagiacometti]

Hi @pabzm
The v1.6.9 seems working perfectly, the jpg image is both visible at the end of the message and as a clickable link on top of the message.

[pabzm]

Can you maybe share the problematic email, e.g. by uploading it as a file to this PR?

If not, could you please show an outline of the messages mime-structure? And if it's multipart/alternative, please check if the image's Content-Id f_m2vz2apx0 is referenced anywhere in the HTML-part?

[gianlucagiacometti]

Here are extracts of the source code from the same message.
The first one (not working) comes straight from Google
The second one is the forward I did to myself with Aquamail from my mobile phone
I just changed the names of senders and recipients for privacy reasons

I checked and the attachment id f_m4n674et0 is only mentioned in this section twice as you can see

NOT WORKING
