Evaluator
- Comment
- "context dependent" seems to point to MiTM attack due to: If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.04.
