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.

Detection & IOCsextracted from sources · hover to see the quote
- →Exploit proof-of-concept uses a write to address 0x414141414141 as a crash indicator; memory corruption crashes in Firefox/Thunderbird JIT context writing to this address are a strong signal of CVE-2019-9791 exploitation. ↗
- →The exploit confuses a Float64Array with a custom UnboxedObject (having fields: slots, elements, buffer, length, byteOffset, data) to gain arbitrary read/write; detection should look for JIT-compiled code that confuses ArrayBufferView objects with plain objects containing those specific field names. ↗
- →Vulnerability is specific to IonMonkey JIT with on-stack replacement (OSR) in constructor functions; monitor for Firefox < 66, Firefox ESR < 60.6, and Thunderbird < 60.6 process crashes originating from JIT-compiled code paths. ↗
- ·The exploit was tested against a local Spidermonkey build and Firefox 65.0.1; behavior may differ across builds or with mitigations enabled. ↗
- ·Thunderbird is generally not exploitable via email because scripting is disabled when reading mail; exploitation risk is limited to browser or browser-like contexts. ↗

Mozilla: Type inference is incorrect for constructors entered through on-stack replacement with IonMonkey
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.
Statement: In general, this flaw be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.
