Original advisory details:

 It was discovered that Firefox was using an out-of-date libusrsctp library.
 An attacker could possibly use this library to perform a reentrancy issue
 on Firefox. (CVE-2022-46871)

 Nika Layzell discovered that Firefox was not performing a check on paste
 received from cross-processes. An attacker could potentially exploit this
 to obtain sensitive information. (CVE-2022-46872)

 Pete Freitag discovered that Firefox did not implement the unsafe-hashes
 CSP directive. An attacker who was able to inject markup into a page
 otherwise protected by a Content Security Policy may have been able to
 inject an executable script. (CVE-2022-46873)

 Matthias Zoellner discovered that Firefox was not keeping the filename
 ending intact when using the drag-and-drop event. An attacker could
 possibly use this issue to add a file with a malicious extension, leading
 to execute arbitrary code. (CVE-2022-46874)

 Hafiizh discovered that Firefox was not handling fullscreen notifications
 when the browser window goes into fullscreen mode. An attacker could
 possibly use this issue to spoof the user and obtain sensitive information.
 (CVE-2022-46877)

 Multiple security issues were discovered in Firefox. If a user were
 tricked into opening a specially crafted website, an attacker could
 potentially exploit these to cause a denial of service, obtain sensitive
 information across domains, or execute arbitrary code. (CVE-2022-46878,
 CVE-2022-46879)");
