Mises à jour de sécurité pour Safari 6 à 8

Apple propose une mise à jour de sécurité pour les différentes versions de Safari qu’elle maintient, lesquelles passent en version Safari 8.0.6, 7.1.6, et 6.2.6 sur, respectivement, Yosemite 10.10.3 (pas sur la bêta 10.10.4), Mavericks et Mountain Lion.

Les corrections apportées à WebKit comblent certains trous de sécurité permettant l’exécution de code arbitraire, ou, pire, l’accès root au système de fichiers. Il est donc plus que recommandé d’aller vérifier les mises à jour sur l’App Store.
