An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary files via clipboard-related IPC messages (CVE-2022-46872). A drag-and-dropped file with a long filename could have had its filename truncated to remove the valid extension, leaving a malicious extension in its place. This could potentially led to user confusion and the execution of malicious code (CVE-2022-46874). Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox ESR 102.5. 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-2022-46878). A missing check related to tex units could have led to a use-after-free in WebGL and potentially exploitable crash (CVE-2022-46880). An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a potentially exploitable crash (CVE-2022-46881). A use-after-free in WebGL extensions could have led to a potentially exploitable crash (CVE-2022-46882).
