Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited

This could lead to unexpected behaviors including; settings being changed, fingerprinting of the system leading to targeted scams, and not triggering the malicious software if McAfee software is detected.
