#CVE-2024-8388: Fullscreen notice on Android could be hidden under various panels and OS prompts
- Reporter
- Shaheen Fazim, Raphael Saniyazov, Rifa'i Rejal Maynando, James Lee, P Umar Farooq, Hafiizh
- Impact
- moderate
Description
Multiple prompts and panels from both Firefox and the Android OS could be used to obscure the notification announcing the transition to fullscreen mode after the fix for CVE-2023-6870 in Firefox 121. This could lead to spoofing the browser UI if the sudden appearance of the prompt distracted the user from noticing the visual transition happening behind the prompt. These notifications now use the Android Toast feature.
This bug only affects Firefox on Android. Other operating systems are unaffected.

- Reporter
- Gregory Pappas
- Impact
- moderate
Description
Internal browser event interfaces were exposed to web content when privileged EventHandler listener callbacks ran for those events. Web content that tried to use those interfaces would not be able to use them with elevated privileges, but their presence would indicate certain browser features had been used, such as when a user opened the Dev Tools console.

#CVE-2024-8383: Firefox did not ask before openings news: links in an external application
- Reporter
- D7
- Impact
- moderate
Description
Firefox normally asks for confirmation before asking the operating system to find an application to handle a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an unscrupulous program that the user downloaded could register itself as a handler. The website that served the application download could then launch that application at will.

Description
Memory safety bugs present in Firefox 129, Firefox ESR 128.1, and Thunderbird 128.1. 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.
