CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 1CVE-2017-7818 – Mozilla: Use-after-free during ARIA array manipulation (MFSA 2017-22)
https://notcve.org/view.php?id=CVE-2017-7818
A use-after-free vulnerability can occur when manipulating arrays of Accessible Rich Internet Applications (ARIA) elements within containers through the DOM. 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 se manipulan arrays de elementos ARIA (Accesible Rich Internet Applications) en los contenedores mediante el DOM. 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=1363723 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 •

An error occurs in the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result "POINT_AT_INFINITY" when it should not. A man-in-the-middle attacker could use this to interfere with a connection, resulting in an attacked party computing an incorrect shared secret. This vulnerability affects Firefox < 55. Ocurre un error en el algoritmo de suma de puntos de curva elíptica que emplea coordenadas mixtas Jacobian-affine que pueden dar como resultado "POINT_AT_INFINITY", aunque no deberían. Un atacante Man-in-the-Middle (MitM) podría aprovecharlo para interferir con una conexión, lo que resulta en que la parte atacada calcula un secreto compartido de forma incorrecta. • http://www.securityfocus.com/bid/100383 http://www.securitytracker.com/id/1039124 https://bugzilla.mozilla.org/show_bug.cgi?id=1352039 https://www.mozilla.org/security/advisories/mfsa2017-18 •
CVSS: 7.5EPSS: 3%CPEs: 1EXPL: 2CVE-2017-7783 – Mozilla Firefox < 55 - Denial of Service
https://notcve.org/view.php?id=CVE-2017-7783
If a long user name is used in a username/password combination in a site URL (such as " http://UserName:Password@example.com"), the resulting modal prompt will hang in a non-responsive state or crash, causing a denial of service. This vulnerability affects Firefox < 55. Si se emplea un nombre de usuario largo en una combinación nombre de usuario/contraseña en una URL de un sitio (como " http://NombreUsuario:Contraseña@ejemplo.com"), el mensaje modal resultante se mantendrá en un estado sin respuesta o se cerrará inesperadamente, provocando una denegación de servicio (DoS). La vulnerabilidad afecta a Firefox en versiones anteriores a la 55. Mozilla Firefox versions prior to 55 suffer from a long username denial of service vulnerability. • https://www.exploit-db.com/exploits/43020 http://www.securityfocus.com/bid/100401 http://www.securitytracker.com/id/1039124 https://bugzilla.mozilla.org/show_bug.cgi?id=1360842 https://www.mozilla.org/security/advisories/mfsa2017-18 • CWE-20: Improper Input Validation •

If a server sends two Strict-Transport-Security (STS) headers for a single connection, they will be rejected as invalid and HTTP Strict Transport Security (HSTS) will not be enabled for the connection. This vulnerability affects Firefox < 55. Si un servidor envía dos cabeceras Strict-Transport-Security (STS) para una única conexión, serán rechazadas com inválidas y no se habilitará HTTP Strict Transport Security (HSTS) para la conexión. La vulnerabilidad afecta a Firefox en versiones anteriores a la 55. • http://www.securityfocus.com/bid/100374 http://www.securitytracker.com/id/1039124 https://bugzilla.mozilla.org/show_bug.cgi?id=1074642 https://www.mozilla.org/security/advisories/mfsa2017-18 •

JavaScript in the "about:webrtc" page is not sanitized properly being assigned to "innerHTML". Data on this page is supplied by WebRTC usage and is not under third-party control, making this difficult to exploit, but the vulnerability could possibly be used for a cross-site scripting (XSS) attack. This vulnerability affects Firefox < 55. No se sanea correctamente el JavaScript en la página "about:webrtc" antes de asignarse a "innerHTML". Los datos en esta página son proporcionados por el uso de WebRTC y no está bajo control de terceros, lo que dificulta su explotación, pero la vulnerabilidad podría emplearse para realizar ataques de Cross-Site Scripting (XSS). • http://www.securityfocus.com/bid/100377 http://www.securitytracker.com/id/1039124 https://bugzilla.mozilla.org/show_bug.cgi?id=1372509 https://www.mozilla.org/security/advisories/mfsa2017-18 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
