https://notcve.org/view.php?id=CVE-2020-12387
A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This resulted in a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. Una condición de carrera cuando se ejecuta el código shutdown para Web Worker conllevo a una vulnerabilidad de uso de la memoria previamente liberada. Esto resultó en un bloqueo potencialmente explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1545345 https://security.gentoo.org/glsa/202005-03 https://security.gentoo.org/glsa/202005-04 https://usn.ubuntu.com/4373-1 https://www.mozilla.org/security/advisories/mfsa2020-16 https://www.mozilla.org/security/advisories/mfsa2020-17 https://www.mozilla.org/security/advisories/mfsa2020-18 https://access.redhat.com/security/cve/CVE-2020-12387 https://bugzilla.redhat.com/show_bug.cgi?id=1831761 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-12395
Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. Los desarrolladores de Mozilla y los miembros de la comunidad informaron bugs de seguridad de la memoria presentes en Firefox versión 75 y Firefox ESR versión 68.7.

https://notcve.org/view.php?id=CVE-2020-6831
A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. Podría presentarse un desbordamiento del búfer cuando se analizan y comprueban fragmentos SCTP en WebRTC.

https://notcve.org/view.php?id=CVE-2020-12392
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. La funcionalidad "Copy as cURL" de la pestaña de red de Devtools no escapa apropiadamente los datos HTTP POST de una petición, que el sitio web puede controlar. Si un usuario usó la funcionalidad "Copy as cURL" y pegó el comando a un terminal, podría haber resultado en la divulgación de archivos locales. • https://bugzilla.mozilla.org/show_bug.cgi?id=1614468 https://security.gentoo.org/glsa/202005-03 https://security.gentoo.org/glsa/202005-04 https://usn.ubuntu.com/4373-1 https://www.mozilla.org/security/advisories/mfsa2020-16 https://www.mozilla.org/security/advisories/mfsa2020-17 https://www.mozilla.org/security/advisories/mfsa2020-18 https://access.redhat.com/security/cve/CVE-2020-12392 https://bugzilla.redhat.com/show_bug.cgi?id=1831764 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-552: Files or Directories Accessible to External Parties •
