CVSS: 8.8EPSS: 89%CPEs: 49EXPL: 2CVE-2015-4495 – Mozilla Firefox Security Feature Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2015-4495
The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015. Vulnerabilidad en el lector de PDF en Mozilla Firefox en versiones anteriores a 39.0.3, Firefox ESR 38.x en versiones anteriores a 38.1.1 y Firefox OS en versiones anteriores a 2.2, permite a atacantes remotos eludir la Same Origin Policy y leer archivos arbitrarios u obtener privilegios a través de vectores que implican código JavaScript manipulado y un setter nativo, tal como se explotó activamente en agosto de 2015. A flaw was discovered in Mozilla Firefox that could be used to violate the same-origin policy and inject web script into a non-privileged part of the built-in PDF file viewer (PDF.js). An attacker could create a malicious web page that, when viewed by a victim, could steal arbitrary files (including private SSH keys, the /etc/passwd file, and other potentially sensitive files) from the system running Firefox. Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges. • https://www.exploit-db.com/exploits/37772 https://github.com/vincd/CVE-2015-4495 http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://lists.opensuse.org/opensuse-security- •
CVSS: 4.3EPSS: 0%CPEs: 25EXPL: 0CVE-2015-2730 – NSS: ECDSA signature validation fails to handle some signatures correctly (MFSA 2015-64)
https://notcve.org/view.php?id=CVE-2015-2730
Mozilla Network Security Services (NSS) before 3.19.1, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and other products, does not properly perform Elliptical Curve Cryptography (ECC) multiplications, which makes it easier for remote attackers to spoof ECDSA signatures via unspecified vectors. Mozilla Network Security Services (NSS) anterior a 3.19.1, utilizado en Mozilla Firefox anterior a 39.0, Firefox ESR 31.x anterior a 31.8 y 38.x anterior a 38.1, y otros productos, no realiza correctamente las multiplicaciones Elliptical Curve Cryptography (ECC), lo que facilita a atacantes remotos falsificar firmas ECDSA a través de vectores no especificados. A flaw was found in the way NSS verified certain ECDSA (Elliptic Curve Digital Signature Algorithm) signatures. Under certain conditions, an attacker could use this flaw to conduct signature forgery attacks. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://rhn.redhat.com/errata/RHSA-2015-1664.html http://rhn.redhat.com/errata/RHSA-2015-1699.html http://www.debian.org&#x • CWE-310: Cryptographic Issues CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 5.1EPSS: 0%CPEs: 30EXPL: 1CVE-2015-2721 – NSS: incorrectly permited skipping of ServerKeyExchange (MFSA 2015-71)
https://notcve.org/view.php?id=CVE-2015-2721
Mozilla Network Security Services (NSS) before 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue. Mozilla Network Security Services (NSS) anterior a 3.19, utilizado en Mozilla Firefox anterior a 39.0, Firefox ESR 31.x anterior a 31.8 y 38.x anterior a 38.1, Thunderbird anterior a 38.1, y otros productos, no determina correctamente las transiciones de estado para la máquina de estados TLS, lo que permite a atacantes man-in-the-middle derrotar los mecanismos de protección criptográfica mediante el bloqueo de mensajes, tal y como fue demostrado mediante la eliminación de una propiedad de confidencialidad adelantada mediante el bloqueo de un mensaje ServerKeyExchange, también conocido como un problema de 'SMACK SKIP-TLS' . It was found that NSS permitted skipping of the ServerKeyExchange packet during a handshake involving ECDHE (Elliptic Curve Diffie-Hellman key Exchange). A remote attacker could use this flaw to bypass the forward-secrecy of a TLS/SSL connection. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://rhn.redhat.com/errata/RHSA-2015-1185.html http://rhn.redhat.com/errata/RHSA-2015-1664.html http://www.debian.org&#x • CWE-310: Cryptographic Issues CWE-358: Improperly Implemented Security Check for Standard •

Mozilla Firefox 38.0 and Firefox ESR 38.0 allow user-assisted remote attackers to read arbitrary files or execute arbitrary JavaScript code with chrome privileges via a crafted web site that is accessed with unspecified mouse and keyboard actions. NOTE: this vulnerability exists because of a CVE-2015-0821 regression. Mozilla Firefox 38.0 y Firefox ESR 38.0 permiten a atacantes remotos asistidos por usuario leer ficheros arbitrarios o ejecutar código JavaScript arbitrario con privilegios chrome a través de un sitio web al que se accede con acciones de ratón y teclado no especificadas. NOTA: esta vulnerabilidad existe debido a una regresión del CVE-2015-0821. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://rhn.redhat.com/errata/RHSA-2015-1207.html http://www.mozilla.org/security/announce/2015/mfsa2015-60.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/75541 http://www.securitytracker.com/id/1032783 http://www.ubuntu.com/usn/USN-2656-1 http://www.ubuntu.com/usn/USN-2656-2 https://bugzilla.mozilla.org/show_bug.cgi?id=1163422 https& • CWE-20: Improper Input Validation •
CVSS: 4.3EPSS: 0%CPEs: 17EXPL: 0CVE-2015-2741 – Mozilla: Key pinning is ignored when overridable errors are encountered (MFSA 2015-67)
https://notcve.org/view.php?id=CVE-2015-2741
Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 do not enforce key pinning upon encountering an X.509 certificate problem that generates a user dialog, which allows user-assisted man-in-the-middle attackers to bypass intended access restrictions by triggering a (1) expired certificate or (2) mismatched hostname for a domain with pinning enabled. Mozilla Firefox anterior a 39.0, Firefox ESR 38.x anterior a 38.1, y Thunderbird anterior a 38.1 no refuerzan la fijación (pinning) de las claves cuando encuentre un problema con los certificados X.509 que genere un dialogo de usuario, lo que permite a atacantes man-in-the-middle asistidos por usuario evadir las restricciones de acceso mediante la provocación de (1) un certificado caducado o (2) un nombre de anfitrión malasociado para un dominio con la fijación (pinning) habilitado. It was found that Firefox skipped key-pinning checks when handling an error that could be overridden by the user (for example an expired certificate error). This flaw allowed a user to override a pinned certificate, which is an action the user should not be able to perform. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00025.html http://rhn.redhat.com/errata/RHSA-2015-1207.html http://rhn.redhat.com/errata/RHSA-2015-1455.html http://www.mozilla.org/security/announce/2015/mfsa2015-67.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.securityfocus.com/bid/75541 http://www.securitytracker.com/id/1032783 http://www.securityt • CWE-310: Cryptographic Issues •
