            Bug ID: 498207
           Summary: Instance of a corrupted image with kitty and iterm2
                    protocol
    Classification: Applications
           Product: konsole
           Version: 24.12.0
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org

Created attachment 177070
  --> https://bugs.kde.org/attachment.cgi?id=177070&action=edit
A tar file with the original and (kitty and iterm2)-encoded form, as well as a
screenshot

SUMMARY

The image in the attached tar file is corrupted when emitted on konsole. Tested
with 24.12.0, but also verified with an older (23.08.x version). (I am on NixOS
if that is relevant)

STEPS TO REPRODUCE
1. Unpack tar file. It contains the same image in multiple forms; the
*-encoded.cat contain kitty and iterm2 encoded images, so can be directly
cat-ed to the terminal.
2. cat bug/kitty-encoded-bug.cat bug/iterm2-encoded-bug.cat 

OBSERVED RESULT
The output looks garbled and not in the right aspect ratio. I've added a
screenshot bug/garbled-output-screenshot.png  how it looks on my machine.

EXPECTED RESULT
The expected output should look like bug/original-image.png

SOFTWARE/OS VERSIONSLinux/KDE Plasma:  NixOS on plasma 6 and 5

ADDITIONAL INFORMATION
The corresponding images look correct on other terminals; e.g. catting the
bug/kitty-encoded-bug.cat on a kitty terminal shows the correct image.

I am maintaining https://timg.sh/ and I discovered it during some manual
testing.

I suspect there is some buffer overflow corruption going on, so this might as
well be a security issue.
