# CVE-2023-37207: Fullscreen notification obscured

# CVE-2023-37211: Memory safety bugs fixed in Firefox 115, Firefox ESR 102.13,
and Thunderbird 102.13
Reporter: Andrew McCreight, Matthew Gaudet, Tom Ritter, and the Mozilla Fuzzing Team,
Impact: high
Description
Memory safety bugs present in Firefox 114, Firefox ESR 102.12, and Thunderbird
102.12. 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.
