Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon Ubuntu (moyenne).

Description

The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 84.
