Is this vulnerability remotely exploitable?

Yes, if an application exposes a remote interface (such as an upload endpoint or email ingestion pipeline) that processes untrusted MSG files with `partition_msg`, an attacker can exploit the issue remotely by supplying crafted MSG documents.

What level of access does an attacker need to exploit this?

The attacker must be able to cause the vulnerable application or service to process a malicious MSG file—typically via file upload, email submission, or control over an upstream data source. No direct shell or filesystem access is required beyond this ability to influence the processed input.

What is the safest general fix pattern?

The safest approach is to treat attachment filenames and paths as untrusted data, enforce a strict base directory for all extracted files, normalize and validate paths before use, and reject any attachment whose resolved path would escape the intended directory. Complement this with least-privilege execution and filesystem permissions to limit damage if a flaw reappears.
