Summary
If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only affects Firefox on Windows when run in non-standard configurations (such as using `runas`). Other operating systems are unaffected. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
