Binaries that cause failure about cwe_checker HOT 4 CLOSED

Thanks for finding all these cases for us! :-) I will add more comments as I go through the list.

The Rust library goblin, that we use to parse ELF files is throwing an error, that it cannot parse the file. After updating the dependency to the newest version one gets a better error message as to why: Apparently, the ELF file contains some non-utf8 characters in section names where goblin expects utf8. This is either a bug in the goblin library or a malformed ELF file. One would probably have to read up what the ELF file standard says to find out which one of the two it is.

xfwm4, tmux and btrfs-image

Here we also get an error when parsing the binary with goblin. Since I also get a lot of warnings when using readelf on the same binary, I am assuming that the ELF file is malformed and thus simply out-of-scope for the cwe_checker for now.

Bash

Yes, the problem lies with Ghidra here. If this also happens with the newest Ghidra version, would you file an issue in the Ghidra repository for that? Thanks! :-)

cherrytree

This looks like a bug contained in the cwe_checker. I will edit this comment when I have pinpointed the root cause.
Edit: Found it. It is an error in the code that parses the Ghidra output into the cwe_checker. I should be able to fix this next week.

The bug uncovered by the cherrytree binary was fixed in PR #251. For the other binaries the failures are either due to malformed ELF files (which at least for the near future are out-of-scope for the cwe_checker) or the bug in question is not contained in the cwe_checker itself (the bash binary), I am closing the issue. Feel free to reopen if I overlooked some cwe_checker-specific problem!
