An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a potentially exploitable crash (CVE-2022-26381). When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen notification (CVE-2022-26383). If an attacker could control the contents of an iframe sandboxed with allow-popups but not allow-scripts, they were able to craft a link that, when clicked, would lead to JavaScript execution in violation of the sandbox (CVE-2022-26384). Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in /tmp, but this behavior was changed to download them to /tmp where they could be affected by other local users. This behavior was reverted to the original, user-specific directory (CVE-2022-26386). When installing an add-on, Firefox verified the signature before prompting the user; but while the user was confirming the prompt, the underlying add-on file could have been modified and Firefox would not have noticed (CVE-2022-26387).
