Issue Overview:

The Mozilla Foundation Security Advisory describes this flaw as: When removing data about an origin whose tab was recently closed, a use-after-free could occur in the Quota manager, resulting in a potentially exploitable crash. (CVE-2020-6805)

The Mozilla Foundation Security Advisory describes this flaw as: The inputs to sctp_load_addresses_from_init are verified by sctp_arethere_unrecognized_parameters; however, the two functions handled parameter bounds differently, resulting in out of bounds reads when parameters are partially outside a chunk. (CVE-2019-20503)

The Mozilla Foundation Security Advisory describes this flaw as: By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash. (CVE-2020-6806)

The Mozilla Foundation Security Advisory describes this flaw as: When a device was changed while a stream was about to be destroyed, the stream-reinit task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash. (CVE-2020-6807)

The Mozilla Foundation Security Advisory describes this flaw as: The first time AirPods are connected to an iPhone, they become named after the user’s name by default (e.g. Jane Doe’s AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user’s name. To resolve this issue, Firefox added a special case that renames devices containing the substring ‘AirPods’ to simply ‘AirPods’. (CVE-2020-6812)

The Mozilla Foundation Security Advisory describes this flaw as: The ‘Copy as cURL’ feature of Devtools’ network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the ‘Copy as Curl’ feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. (CVE-2020-6811)

The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers and community members reported memory safety bugs present in Firefox 73 and Firefox ESR 68.5. 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. (CVE-2020-6814)
