CERTFR-2020-ALE-023

Vulnerability from certfr_alerte

De multiples vulnérabilités ont été découvertes dans Google Chrome. Elles permettent à un attaquant de provoquer une exécution de code arbitraire à distance et un contournement de la politique de sécurité.

Plusieurs sources, dont Google, confirment que ces vulnérabilités sont actuellement utilisées dans le cadre d'attaques ciblées via des codes Javascript intégrés dans des sites Web déjà compromis. Pour certains d'entre elles, des preuves de concept sont disponibles publiquement.

Solution

Le CERT FR recommande d'appliquer la mise à jour de Google Chrome sans délai. Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
