#CVE-2020-15652: Potential leak of redirect targets when loading scripts in a worker
Impact- high
Description
By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script.
#CVE-2020-6514: WebRTC data channel leaks internal address to peer
Impact: high
Description
WebRTC used the memory address of a class instance as a connection identifier. Unfortunately, this value is often transmitted to the peer, which allows bypassing ASLR.
#CVE-2020-15655: Extension APIs could be used to bypass Same-Origin Policy
Impact: high
Description
Mozilla Developer Rob Wu discovered that a redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information.

Impact: high
Description
Mozilla developers and community members Kevin Brosnan, Alexandru Michis, Natalia Csoregi, Jason Kratzer, Christian Holler, Simon Giesecke, Luke Wagner reported memory safety bugs present in Firefox 78. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
