#CVE-2024-2612: Self referencing object could have potentially led to a use-after-free
- Reporter
- Ronald Crane
- Impact
- moderate
Description
If an attacker could find a way to trigger a particular code path in SafeRefPtr, it could have triggered a crash or potentially be leveraged to achieve code execution.

#CVE-2024-2614: Memory safety bugs fixed in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9
- Reporter
- Noah Lokocz, Kevin Brosnan, Ryan VanderMeulen and the Mozilla Fuzzing Team
- Impact
- high
Description
Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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.
