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 •

https://notcve.org/view.php?id=CVE-2019-9788
Mozilla developers and community members reported memory safety bugs present in Firefox 65, Firefox ESR 60.5, and Thunderbird 60.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. Desarrolladores de Mozilla y miembros de la comunidad reportaron bugs en seguridad de memoria presentes en Firefox 65, Firefox ESR 60.5, y Thunderbird 60.5. Algunos de los bugs mostraron evidencias de corrupción de memoria y asumimos que con el suficiente esfuerzo esto podría ser explotado para ejecutar código arbitrario. • https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1518001%2C1521304%2C1521214%2C1506665%2C1516834%2C1518774%2C1524755%2C1523362%2C1524214%2C1529203 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-2019-9788 https://bugzilla.redhat.com/show_bug.cgi?id • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
