assemblyline-service-pefile's Issues

PDB filename parse issue

Many pe sample pdb filenames are not terminated at the trailing null character; filenames often have have trailing characters after the null a long string of null characters.

Example samples:

UnidentifiedImageError: cannot identify image file '/tmp/working_directory/tmpx7zwz0px/RT_ICON_GROUP_0_ICON_0.ico'

Hey,
I'm a tech guy that helps our IR team to upgrade their Infra' for improving their capabilities with AL4.
They are still using AL3 and are craving to make the upgrade stable as possible.

After I've done the setup and tried to scan some sample files I notice that there is an error that occurs for some awkward causes.

The service PEfile (4.1.0.stable5) keep crashing for the following tray:

File "/var/lib/assemblyline/.local/lib/python3.9/site-packages/assemblyline_v4_service/common/base.py", line 133, in handle_task
self.execute(request)
File "/opt/al_service/pe_file/pe_file.py", line 710, in execute
self.get_pe_info(G_LCID)
File "/opt/al_service/pe_file/pe_file.py", line 333, in get_pe_info
image_section.add_image(path, name, 'Extracted RT_ICON')
File "/var/lib/assemblyline/.local/lib/python3.9/site-packages/assemblyline_v4_service/common/result.py", line 320, in add_image
res = self.request.add_image(path, name, description, classification)
File "/var/lib/assemblyline/.local/lib/python3.9/site-packages/assemblyline_v4_service/common/request.py", line 67, in add_image
img = Image.open(path)
File "/var/lib/assemblyline/.local/lib/python3.9/site-packages/PIL/Image.py", line 3030, in open
raise UnidentifiedImageError(
UnidentifiedImageError: cannot identify image file '/tmp/working_directory/tmpx7zwz0px/RT_ICON_GROUP_0_ICON_0.ico'

I've asked for help on the discord channel associated with AL4 - but no answers came from there :)
I would like to know if there could be a work-around to this issue.

Thanks for your contribution :)
