A vulnerability was found in NSS. The NSS client auth crashes without a user
certificate in the database, leading to a segmentation fault or crash

An out of date library (libusrsctp) contained vulnerabilities that could
potentially be exploited (CVE-2022-46871).

By confusing the browser, the fullscreen notification could have been delayed
or suppressed, resulting in potential user confusion or spoofing attacks

Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK
treating all text/plain MIMEs containing file URLs as being dragged a website
could arbitrarily read a file via a call to DataTransfer.setData

Navigations were being allowed when dragging a URL from a cross-origin iframe
into the same tab which could lead to website spoofing attacks

A mishandled security check when creating a WebSocket in a WebWorker caused
the Content Security Policy connect-src header to be ignored. This could lead
to connections to restricted origins from inside WebWorkers (CVE-2023-23602).

Regular expressions used to filter out forbidden properties and values from
style directives in calls to console.log weren't accounting for external URLs,
allowing bypassing Content Security Policy via format directives. Data could
then be potentially exfiltrated from the browser (CVE-2023-23603).

Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs
present in Firefox ESR 102.6. 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-2023-23605).
