https://notcve.org/view.php?id=CVE-2017-7819
A use-after-free vulnerability can occur in design mode when image objects are resized if objects referenced during the resizing have been freed from memory. This results in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando los objetos imagen se redimensionan si los objetos referenciados durante el redimensionamiento se han liberado de la memoria. Esto resulta en un cierre inesperado explotable. • http://www.securityfocus.com/bid/101055 http://www.securitytracker.com/id/1039465 https://access.redhat.com/errata/RHSA-2017:2831 https://access.redhat.com/errata/RHSA-2017:2885 https://bugzilla.mozilla.org/show_bug.cgi?id=1380292 https://lists.debian.org/debian-lts-announce/2017/11/msg00000.html https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3987 https://www.debian.org/security/2017/dsa-4014 https://www.mozilla.org/security/advisor • CWE-416: Use After Free •

Memory safety bugs were reported in Firefox 55 and Firefox ESR 52.3. 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 Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Se han informado de errores de seguridad de memoria en Firefox 55 y Firefox ESR 52.3.

https://notcve.org/view.php?id=CVE-2017-7814
File downloads encoded with "blob:" and "data:" URL elements bypassed normal file download checks though the Phishing and Malware Protection feature and its block lists of suspicious sites and files. This would allow malicious sites to lure users into downloading executables that would otherwise be detected as suspicious. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Las descargas de archivos codificados con elementos URL "blob:" y "data:" omitían las comprobaciones de descarga de archivos normales a pesar de la característica Phishing and Malware Protection y sus listas de bloqueo de páginas y archivos sospechosos. Esto permitiria a los sitios maliciosos engañar a los usuarios para que descarguen ejecutables que, de otra manera, se habrían detectado como sospechosos. • http://www.securityfocus.com/bid/101059 http://www.securitytracker.com/id/1039465 https://access.redhat.com/errata/RHSA-2017:2831 https://access.redhat.com/errata/RHSA-2017:2885 https://bugzilla.mozilla.org/show_bug.cgi?id=1376036 https://lists.debian.org/debian-lts-announce/2017/11/msg00000.html https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3987 https://www.debian.org/security/2017/dsa-4014 https://www.mozilla.org/security/advisor • CWE-20: Improper Input Validation CWE-494: Download of Code Without Integrity Check •

https://notcve.org/view.php?id=CVE-2017-7793
A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada en la API Fetch cuando el trabajador o la ventana asociada se liberan mientras siguen en uso, lo que resulta en un cierre inesperado potencialmente explotable.

https://notcve.org/view.php?id=CVE-2017-7824
A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for WebGL content. This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Ocurre un desbordamiento de búfer cuando se dibujan y validan elementos con la librería de gráficos ANGLE, utilizado para contenidos WebGL.
