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.
