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. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con suficiente esfuerzo algunos de estos podrían haber sido explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1595886%2C1611482%2C1614704%2C1624098%2C1625749%2C1626382%2C1628076%2C1631508 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-2020-12395 https://bugzilla.redhat.com/show • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

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. Esto podría haber provocado una corrupción en la memoria y un bloqueo potencialmente explotable. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00000.html http://packetstormsecurity.com/files/158480/usrsctp-Stack-Buffer-Overflow.html https://bugzilla.mozilla.org/show_bug.cgi?id=1632241 https://security.gentoo.org/glsa/202005-03 https://security.gentoo.org/glsa/202005-04 https://usn.ubuntu.com/4373-1 https://www.debian.org/security/2020/dsa-4714 https://www.mozilla.org/security/advisories/mfsa2020-16 https://www.mozilla.org/security/advisories/mfsa2020-17 https:&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-6828
A malicious Android application could craft an Intent that would have been processed by Firefox for Android and potentially result in a file overwrite in the user's profile directory. One exploitation vector for this would be to supply a user.js file providing arbitrary malicious preference values. Control of arbitrary preferences can lead to sufficient compromise such that it is generally equivalent to arbitrary code execution.<br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. • https://bugzilla.mozilla.org/show_bug.cgi?id=1617928 https://www.mozilla.org/security/advisories/mfsa2020-13 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
