An attacker could have triggered a use-after-free condition when creating a WebRTC connection over HTTPS (CVE-2023-37201). Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free in SpiderMonkey (CVE-2023-37202). A website could have obscured the fullscreen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks (CVE-2023-37207). When opening Diagcab files, Firefox did not warn the user that these files may contain malicious code (CVE-2023-37208). Memory safety bugs present in Firefox ESR 102.12. 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-2023-37211).
