CVSS: 6.1EPSS: 0%CPEs: 7EXPL: 0CVE-2020-15677 – Mozilla: Download origin spoofing via redirect
https://notcve.org/view.php?id=CVE-2020-15677
By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. Al explotar una vulnerabilidad de Redireccionamiento Abierto en un sitio web, un atacante podría haber falsificado el sitio que es mostrado en el cuadro de diálogo del archivo de descarga para mostrar el sitio original (el que sufre el redireccionamiento abierto) en lugar del sitio del que se descargó el archivo realmente. Esta vulnerabilidad afecta a Firefox versiones anteriores a 81, Thunderbird versiones anteriores a 78.3, y Firefox ESR versiones anteriores a 78.3 The Mozilla Foundation Security Advisory describes this flaw as: By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/show_bug.cgi?id=1641487 https://lists.debian.org/debian-lts-announce/2020/10/msg00020.html https://security.gentoo.org/glsa/202010-02 https://www.debian.org/security/2020/dsa-4770 https://www.mozilla.org/security/advisories/mfsa2020-42 https://www.mozilla.org/security/advisories/mfsa2020-43 https://www.mozil • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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 Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. Los desarrolladores de Mozilla reportaron unos bugs de seguridad de la memoria presentes en Firefox versión 80 y Firefox ESR versión 78.2. Algunos de estos bugs han mostrado evidencia de corrupción de la memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/buglist.cgi?bug_id=1648493%2C1660800 https://lists.debian.org/debian-lts-announce/2020/10/msg00020.html https://security.gentoo.org/glsa/202010-02 https://www.debian.org/security/2020/dsa-4770 https://www.mozilla.org/security/advisories/mfsa2020-42 https://www.mozilla.org/security/advisories/mfsa2020-43 https:/&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-416: Use After Free •
CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-15669 – Mozilla: Use-After-Free when aborting an operation
https://notcve.org/view.php?id=CVE-2020-15669
When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12. Cuando se anula una operación, como una recuperación, puede ser eliminada una señal de cancelación mientras se alerta a los objetos que deben ser notificados. Esto resulta en un uso de la memoria previamente liberada y suponemos que con suficiente esfuerzo podría haber sido explotado para ejecutar código arbitrario. • https://bugzilla.mozilla.org/show_bug.cgi?id=1656957 https://www.mozilla.org/security/advisories/mfsa2020-37 https://www.mozilla.org/security/advisories/mfsa2020-40 https://access.redhat.com/security/cve/CVE-2020-15669 https://bugzilla.redhat.com/show_bug.cgi?id=1872532 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-15664
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80. Al mantener una referencia a la función eval() desde una ventana about:blank, una página web maliciosa podría haber conseguido acceso al objeto InstallTrigger, lo que le permitiría solicitar al usuario que instale una extensión. Combinado con la confusión del usuario, esto podría resultar en la instalación de una extensión maliciosa o involuntaria. • https://bugzilla.mozilla.org/show_bug.cgi?id=1658214 https://www.mozilla.org/security/advisories/mfsa2020-36 https://www.mozilla.org/security/advisories/mfsa2020-37 https://www.mozilla.org/security/advisories/mfsa2020-38 https://www.mozilla.org/security/advisories/mfsa2020-39 https://www.mozilla.org/security/advisories/mfsa2020-40 https://www.mozilla.org/security/advisories/mfsa2020-41 https://access.redhat.com/security/cve/CVE-2020-15664 https://bugzilla.redhat.com/show_bug.cgi?id=1872 • CWE-648: Incorrect Use of Privileged APIs CWE-863: Incorrect Authorization •
