Description

The following files trigger antivirus scans which report the presence of the Emf.Exploit.CVE_2017-3122-6335825-0 CVE:

• docs/docs/integrations/document_loaders/example_data/fake.vsdx
• libs/community/tests/examples/fake.vsdx

These files were added in the https://github.com/langchain-ai/langchain/pull/16171 PR.

Details on the scan results: https://www.virustotal.com/gui/file/3b02db67f312bfb1a0ac430673c372ec92eabfaf2888030161d7841ae2120f5f/detection

Recommendation: remove the visio/media/image2.emf entry from the fake.vsdx archive. This is the file which triggers the CVE and it is not required for tests which use the archive.

I assume there's no easy way to test whether the file actually has a malicious payload? As far as I understand, if there were a malicious payload, this would affect users trying to open the file with specific versions of Adobe? I'll remove the example file from the docs -- this feels like a false positive from the antivirus software (but likely no easy way to confirm whether the contents are malicious or not)

Correct. I assume this is a false positive and not actually harmful however it would be better to remove the file regardless since false positives are frustrating and could lead to people adding antivirus rules that ignore harmful files as well.

I came here to report this as well. According to virustotal, only ClamAV identified this as a threat.

I see that the file from the docs directory was removed, but there appears to still be another, with the same hash (b84af575643ac927e21073f336370945), located in the latest master branch here.
