CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2019-9800 – Mozilla: Memory safety bugs fixed in Firefox 67 and Firefox ESR 60.7
https://notcve.org/view.php?id=CVE-2019-9800
Mozilla developers and community members reported memory safety bugs present in Firefox 66, Firefox ESR 60.6, and Thunderbird 60.6. 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 < 60.7, Firefox < 67, and Firefox ESR < 60.7. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de memoria presentes en Firefox versión 66, Firefox ESR versión 60.6 y Thunderbird versión 60.6. Algunos de estos errores mostraron evidencias de corrupción de memoria y presumimos que, con un esfuerzo suficiente, algunos de estos podrían ser explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1540166%2C1534593%2C1546327%2C1540136%2C1538736%2C1538042%2C1535612%2C1499719%2C1499108%2C1538619%2C1535194%2C1516325%2C1542324%2C1542097%2C1532465%2C1533554%2C1541580 https://www.mozilla.org/security/advisories/mfsa2019-13 https://www.mozilla.org/security/advisories/mfsa2019-14 https://www.mozilla.org/security/advisories/mfsa2019-15 https://access.redhat.com/security/cve/CVE-2019-9800 https://bugzilla.redhat.com/show_bug.cgi?id=1712623 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2019-11691 – Mozilla: Use-after-free in XMLHttpRequest
https://notcve.org/view.php?id=CVE-2019-11691
A use-after-free vulnerability can occur when working with XMLHttpRequest (XHR) in an event loop, causing the XHR main thread to be called after it has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. Puede ocurrir una vulnerabilidad de uso después de liberarse cuando se trabaja con XMLHttpRequest (XHR) en un bucle de eventos, lo que hace que se llame al subproceso principal de XHR después de que se haya liberado. Esto da lugar a una caída potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1542465 https://www.mozilla.org/security/advisories/mfsa2019-13 https://www.mozilla.org/security/advisories/mfsa2019-14 https://www.mozilla.org/security/advisories/mfsa2019-15 https://access.redhat.com/security/cve/CVE-2019-11691 https://bugzilla.redhat.com/show_bug.cgi?id=1712617 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2019-9794
A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. • https://bugzilla.mozilla.org/show_bug.cgi?id=1530103 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

https://notcve.org/view.php?id=CVE-2019-9801
Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. • https://bugzilla.mozilla.org/show_bug.cgi?id=1527717 https://www.mozilla.org/security/advisories/mfsa2019-07 https://www.mozilla.org/security/advisories/mfsa2019-08 https://www.mozilla.org/security/advisories/mfsa2019-11 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-18513
A crash can occur when processing a crafted S/MIME message or an XPI package containing a crafted signature. This can be used as a denial-of-service (DOS) attack because Thunderbird reopens the last seen message on restart, triggering the crash again. This vulnerability affects Thunderbird < 60.5. Puede producirse un bloqueo al procesar un mensaje S/MIME elaborado o un paquete XPI que contenga una firma elaborada. Esto puede utilizarse como un ataque de Denegación de Servicio (DOS) porque Thunderbird vuelve a abrir el último mensaje visto en el reinicio, desencadenando el bloqueo de nuevo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1533300 https://www.mozilla.org/security/advisories/mfsa2019-03 • CWE-476: NULL Pointer Dereference •
