CVSS: 9.8EPSS: 22%CPEs: 11EXPL: 3CVE-2019-9791 – Spidermonkey - IonMonkey Type Inference is Incorrect for Constructors Entered via OSR
https://notcve.org/view.php?id=CVE-2019-9791
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. El sistema de inferencia de tipos permite la recopilación de funciones que pueden generar confusiones de tipo entre objetos arbitrarios cuando se compilan por medio del compilador IonMonkey just-in-time (JIT) y cuando se ingresa a la función constructor mediante el reemplazo en la pila (OSR). Esto permite una posible lectura y escritura arbitrarias de objetos durante un bloqueo explotable. • https://www.exploit-db.com/exploits/46613 https://github.com/Sp0pielar/CVE-2019-9791 https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/show_bug.cgi?id=1530958 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 https://access.redhat.com/security/cve/CVE-2019-9791 https://bugzilla.redhat. • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

https://notcve.org/view.php?id=CVE-2019-9795
A vulnerability where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. Una vulnerabilidad de confusión de tipo en compilador IonMonkey just-in-time (JIT) podría ser utilizado por JavaScript malicioso para desencadenar un fallo potencialmente explotable. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 60.6, Firefox ESR versiones anteriores a 60.6 y Firefox versiones anteriores a 66. • https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/show_bug.cgi?id=1514682 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 https://access.redhat.com/security/cve/CVE-2019-9795 https://bugzilla.redhat.com/show_bug.cgi?id=1690680 • CWE-617: Reachable Assertion CWE-787: Out-of-bounds Write CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2019-9796 – Mozilla: Use-after-free with SMIL animation controller
https://notcve.org/view.php?id=CVE-2019-9796
A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. Una vulnerabilidad de uso después de liberación de memoria puede darse cuando el controlador de animación SMIL registra incorrectamente con el controlador de actualización dos veces cuando sólo se espera un único registro. Cuando se libera un registro con la eliminación del elemento de controlador de animación, el controlador de actualización deja incorrectamente un puntero pendiente en la matriz de observadores del controlador. • https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/show_bug.cgi?id=1531277 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 https://access.redhat.com/security/cve/CVE-2019-9796 https://bugzilla.redhat.com/show_bug.cgi?id=1690681 • CWE-416: Use After Free •
CVSS: 9.8EPSS: 17%CPEs: 11EXPL: 3CVE-2019-9792 – Spidermonkey - IonMonkey Leaks JS_OPTIMIZED_OUT Magic Value to Script
https://notcve.org/view.php?id=CVE-2019-9792
The IonMonkey just-in-time (JIT) compiler can leak an internal JS_OPTIMIZED_OUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. El compilador IonMonkey just-in-time (JIT) puede filtrar un valor mágico interno JS_OPTIMIZED_OUT para la ejecución script durante un rescate. JavaScript puede utilizar este valor mágico para lograr daños en la memoria, lo que lleva a un fallo potencialmente explotable. • https://www.exploit-db.com/exploits/46939 http://packetstormsecurity.com/files/153106/Spidermonkey-IonMonkey-JS_OPTIMIZED_OUT-Value-Leak.html https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/show_bug.cgi?id=1532599 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 https://access.redhat.com/security/ • CWE-787: Out-of-bounds Write •
