Severity
+ Critical
Remote
+ Remote
Type
+ Arbitrary code execution

CVE-2019-9802 created at 25 Sep 2019 19:31:40
Severity
+ Medium
Remote
+ Remote
Type
+ Information disclosure
Description
+ If a Sandbox content process is compromised in Firefox before 66.0, 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.

CVE-2019-9803 created at 25 Sep 2019 19:31:40
Severity
+ Medium
Remote
+ Remote
Type
+ Access restriction bypass
Description
+ The Upgrade-Insecure-Requests (UIR) specification states that if UIR is enabled through Content Security Policy (CSP), navigation to a same-origin URL must be upgraded to HTTPS. Firefox before 66.0 will incorrectly navigate to an HTTP URL rather than perform the security upgrade requested by the CSP in some circumstances, allowing for potential man-in-the-middle attacks on the linked resources.
