CVE-2019-9802
Last modified
CVE-2019-9802 is a vulnerability of currently unknown severity. If a Sandbox content process is compromised, it can initiate an FTP download which will then use a child process to render the downloaded data. The downloaded data can then be passed to the Chrome process with an arbitrary file length supplied by an attacker, bypassing sandbox protections and allow for a potential memory read of adjacent data from the privileged Chrome process, which may include sensitive data. EPSS estimates a 1.13% chance of exploitation in the next 30 days.
