References o Bug 1610880 # CVE-2020-6806: BodyStream::OnInputStreamReady was missing protections against state confusion Reporter Sergei Glazunov of Google Project Zero Impact high Description 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. References o Bug 1612308 # CVE-2020-6807: Use-after-free in cubeb during stream destruction Reporter C.M.Chang Impact high Description 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. References o Bug 1614971 # CVE-2020-6811: Devtools' 'Copy as cURL' feature did not fully escape website-controlled data, potentially leading to command injection Reporter Ophir LOJKINE Impact moderate Description 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. References o Bug 1607742 # CVE-2019-20503: Out of bounds reads in sctp_load_addresses_from_init Reporter Natalie Silvanovich of Google Project Zero Impact moderate Description 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. References o Bug 1613765 # CVE-2020-6812: The names of AirPods with personally identifiable information were exposed to websites with camera or microphone permission Reporter Jan-Ivar Bruaroey Impact moderate Description 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'. References o Bug 1616661 # CVE-2020-6814: Memory safety bugs fixed in Firefox 74 and Firefox ESR 68.6 Reporter Mozilla developers and community Impact high Description Mozilla developers and community members Byron Campen, Jason Kratzer, and Christian Holler 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.
