CVE-2019-9791
N/A
N/A
Summary
The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
Affected Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
| Mozilla | Thunderbird | unspecified < 60.6 | affected |
| Mozilla | Firefox ESR | unspecified < 60.6 | affected |
| Mozilla | Firefox | unspecified < 66 | affected |
