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 •
