https://notcve.org/view.php?id=CVE-2019-17010
Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. Bajo determinadas condiciones, cuando se comprueba la preferencia Resist Fingerprinting durante las verificaciones de orientación del dispositivo, una condición de carrera podría haber causado un uso de la memoria previamente liberada y un bloqueo explotable potencialmente. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a la versión 68.3, Firefox ESR versiones anteriores a la versión 68.3 y Firefox versiones anteriores a la versión 71. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00001.html https://access.redhat.com/errata/RHSA-2020:0292 https://access.redhat.com/errata/RHSA-2020:0295 https://bugzilla.mozilla.org/show_bug.cgi?id=1581084 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4241-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/secur • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2019-17012
Mozilla developers reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. 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 Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. Los desarrolladores de Mozilla reportaron bugs de seguridad de memoria presentes en Firefox versión 70 y Firefox ESR versión 68.2. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con un esfuerzo suficiente algunos de estos podrían haber sido explotados para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00001.html https://access.redhat.com/errata/RHSA-2020:0292 https://access.redhat.com/errata/RHSA-2020:0295 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1449736%2C1533957%2C1560667%2C1567209%2C1580288%2C1585760%2C1592502 https://security.gentoo.org/glsa/202003-02 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4241-1 https://usn.ubun • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
