Description James Olson 2019-03-04 17:00:39 UTC 
Description of problem:
Attempted to see if a jpg file which wouldn't display in Firefox (says errors inside the file) was really some other file type e.g. png under the hood.
I figured the filename extension was wrong. The file command crashed instead:

Ran from the command line as a regular user:
lansdale:~> file /run/media/jolson/USB20FD/TD_QEE.jpg 
free(): double free detected in tcache 2
Aborted (core dumped)
lansdale:~> 

I can upload the (presumably damaged) file, just need a ticket# to attach it if I'm allowed.

Comment 1 James Olson 2019-03-04 17:15:36 UTC 
I attempted to read TD_QEE.jpg and getting an I/O error, likely the VFAT filesystem on USB stick is damaged. This means I can't upload it. Using ls -l, I see the file is 59099 bytes in size, permissions 644 jolson:users, and I'm using the jolson account (owner) to access.

I ran fsck earlier today after first seeing the crash in the 'file' command. That did not fix the I/O problem with this file (bad blocks??). I'm thinking the I/O error is not being handled correctly at the application level, leading to the double-free error I saw.

Interesting, I ran hexdump and it was able to dump the first 0x2000 (8KiB) bytes before hitting the I/O error. (A bad block is likely.)
I am pasting part of the hexdump that I got. I removed a chunk to save space here.

I found a good copy of the input file on my hard drive, attaching it.

Created attachment 1540795 [details]
Music concert announcement

This is a working copy of the file that caused the 'file' command to crash with a "double-free" error.
Comment 4 Kamil Dudka 2019-03-05 09:13:53 UTC 
I suspect that the crash must have been caused by the I/O failure.  Are you able to crash file(1) if you run it on attachment #1540795 [details]?
