Vulnerability from certfr_alerte - Published: - Updated:
Le 3 avril 2020, Mozilla a publié des correctifs pour deux vulnérabilités affectant le navigateur Firefox.
Mozilla annonce que ces deux vulnérabilités, qui permettent une exécution de code arbitraire à distance, sont activement exploitées dans le cadre d'attaques ciblées.
Le CERT-FR recommande l’application de la mise à jour dans les plus brefs délais. Lorsque cela n'est pas possible, le CERT-FR recommande l'utilisation d'un autre navigateur, à condition que celui-ci dispose des dernières mises à jour de sécurité.
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
