CVE-2018-6152

Estado: ModificadaCrítica (9.6)—

The implementation of the Page.downloadBehavior backend unconditionally marked downloaded files as safe, regardless of file type in Google Chrome prior to 66.0.3359.117 allowed an attacker who convinced a user to install a malicious extension to potentially perform a sandbox escape via a crafted HTML page and user interaction.
