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
Buffer overflow in curl earlier than 6.0-1.1, and curl-ssl earlier than 6.0-1.2, allows remote attackers to execute arbitrary commands by forcing a long error message to be generated.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
