CVE-2019-11738 – Mozilla: Content security policy bypass through hash-based sources in directives

https://notcve.org/view.php?id=CVE-2019-11738

If a Content Security Policy (CSP) directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1. Si una directiva de Content Security Policy (CSP) se define que usa una fuente basada en hash que toma la cadena vacía como entrada, se permitirá la ejecución de cualquier URI javascript:. Esto podría permitir que contenido malicioso de JavaScript sea ejecutado, sin pasar por los permisos de CSP. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1452037 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11738 https://bugzilla.redhat.com/show_bug.cgi?id=1748663 • CWE-358: Improperly Implemented Security Check for Standard •

CVE-2019-11742 – Mozilla: Same-origin policy violation with SVG filters and canvas to steal cross-origin images

https://notcve.org/view.php?id=CVE-2019-11742

A same-origin policy violation occurs allowing the theft of cross-origin images through a combination of SVG filters and a &lt;canvas&gt; element due to an error in how same-origin policy is applied to cached image content. The resulting same-origin policy violation could allow for data theft. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Se presenta una violación de la política del mismo origen, que permite el robo de imágenes de origen cruzado por medio de una combinación de filtros SVG y un elemento &lt;canvas&gt; debido a un error en cómo es aplicada la política del mismo origen para el contenido de imagen en la memoria caché. La violación de la política del mismo origen resultante podría permitir el robo de datos. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1559715 https://security.gentoo.org/glsa/201911-07 https://usn.ubuntu.com/4150-1 https://www.mozilla.org/security/advisories/mfsa2019-25 https://w • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

CVE-2019-11743 – Mozilla: Cross-origin access to unload event attributes

https://notcve.org/view.php?id=CVE-2019-11743

Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Los eventos de navegación no se adhirieron totalmente a la especificación borrador del "Navigation-Timing Level 2" de W3C en algunas instancias para el evento de descarga, que restringe el acceso a los atributos de sincronización detallados para que solo sean del mismo origen. Esto resultó en una posible exposición de información de origen cruzado mediante la sincronización de ataques de canal lateral. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1560495 https://security.gentoo.org/glsa/201911-07 https://usn.ubuntu.com/4150-1 https://w3c.github.io/navigation-timing https://www.mozilla.org • CWE-203: Observable Discrepancy CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
