PDF scan fails with particular PDF #1333

Describe the bug

A particular PDF file cannot be scanned with clamav. The following error occurs:

clamav-1  | LibClamAV Error: pdf_extract_obj: can't create temporary file /tmp/20240815_121615-clamsmtpd.OPMkpg.6bb1fd3610/clamsmtpd.OPMkpg.286cc89e71/_root_personalblatt_logo_hfe.pdf.7a44f2b420/pdf-tmp.99c16273bf/pdf obj 338 0: File exists

clamav-1  | Thu Aug 15 12:16:15 2024 -> /var/spool/clamsmtp/clamsmtpd.OPMkpg: Can't create temporary file ERROR

It seems it tries to extract an object that already exists with the same name?

This PDF was generated with the Adobe PDF Library 19.10.96. Any other files, PDF and other formats, can be scanned.

Closing this issue. It was caused by me having LeaveTemporaryFiles set to yes during setting up clamav. Didn't expect it to cause issues during scans.

@alexzeitgeist that's interesting. Still a bug, but not one that affects most people. 🤔
