CVSS: 10.0EPSS: 0%CPEs: 17EXPL: 0CVE-2017-7826 – Mozilla: Memory safety bugs fixed in Firefox 57 and Firefox ESR 52.5 (MFSA 2017-25)
https://notcve.org/view.php?id=CVE-2017-7826
Memory safety bugs were reported in Firefox 56 and Firefox ESR 52.4. 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 < 57, Firefox ESR < 52.5, and Thunderbird < 52.5. Se han informado de errores de seguridad de memoria en Firefox 56 y Firefox ESR 52.4.

If web content on a page is dragged onto portions of the browser UI, such as the tab bar, links can be opened that otherwise would not be allowed to open. This can allow malicious web content to open a locally stored file through "file:" URLs. This vulnerability affects Firefox < 56. Si el contenido web en una página se arrastra a porciones de la interfaz de usuario del navegador como una barra de pestañas, los enlaces se pueden abrir, algo que de otra manera no se podrían abrir. Esto puede permitir que un contenido web malicioso abra un archivo almacenado localmente mediante URL "file:". • http://www.securityfocus.com/bid/101057 http://www.securitytracker.com/id/1039465 https://bugzilla.mozilla.org/show_bug.cgi?id=1379842 https://www.mozilla.org/security/advisories/mfsa2017-21 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

WebExtensions could use popups and panels in the extension UI to load an "about:" privileged URL, violating security checks that disallow this behavior. This vulnerability affects Firefox < 56. WebExtensions podría utilizar las ventanas emergentes y los paneles en la interfaz de usuario de la extensión para cargar una URL privilegiada "about:", violando las comprobaciones de seguridad que no permiten este comportamiento. Esta vulnerabilidad afecta a las versiones anteriores a la 56 de Firefox. • http://www.securityfocus.com/bid/101057 http://www.securitytracker.com/id/1039465 https://bugzilla.mozilla.org/show_bug.cgi?id=1380597 https://www.mozilla.org/security/advisories/mfsa2017-21 • CWE-20: Improper Input Validation •

The "instanceof" operator can bypass the Xray wrapper mechanism. When called on web content from the browser itself or an extension the web content can provide its own result for that operator, possibly tricking the browser or extension into mishandling the element. This vulnerability affects Firefox < 56. El operador "instanceof" puede omitir el mecanismo del wrapper Xray. Cuando se le llama en un contenido web desde el propio navegador o una extensión, el contenido web puede proporcionar su propio resultado para ese operador, pudiendo engañar al navegador o extensión para que manipule erróneamente el elemento. • http://www.securityfocus.com/bid/101057 http://www.securitytracker.com/id/1039465 https://bugzilla.mozilla.org/show_bug.cgi?id=1378207 https://www.mozilla.org/security/advisories/mfsa2017-21 •
