CVE-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 • CWE-310: Cryptographic Issues CWE-358: Improperly Implemented Security Check for Standard •

CVE-2014-1490 – nss: TOCTOU, potential use-after-free in libssl's session ticket processing (MFSA 2014-12)
https://notcve.org/view.php?id=CVE-2014-1490
Race condition in libssl in Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via vectors involving a resumption handshake that triggers incorrect replacement of a session ticket. Condición de carrera en libssl en Mozilla Network Security Services (NSS) anterior a 3.15.4, utilizado en Mozilla Firefox anterior a 27.0, Firefox ESR 24.x anterior a 24.3, Thunderbird anterior a 24.3, SeaMonkey anterior a 2.24 y otros productos, permite a atacantes remotos causar una denegación de servicio (uso después de liberación) o posiblemente tener otro impacto no especificado a través de vectores que involucran una reanudación de handshake que provoca un reemplazo incorrecto de un ticket de sesión. A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127966.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/129218.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2014-1491 – nss: Do not allow p-1 as a public DH value (MFSA 2014-12)
https://notcve.org/view.php?id=CVE-2014-1491
Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value. Mozilla Network Security Services (NSS) anterior a 3.15.4, utilizado en Mozilla Firefox anterior a 27.0, Firefox ESR 24.x anterior a 24.3, Thunderbird anterior a 24.3, SeaMonkey anterior a 2.24 y otros productos, no restringe debidamente los valores públicos en el intercambio de claves de Diffie-Hellman, lo que facilita a atacantes remotos evadir mecanismos de protección criptográfica en el manejo de tickets mediante el aprovechamiento de un cierto valor. It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server. • http://hg.mozilla.org/projects/nss/rev/12c42006aed8 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127966.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/129218.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00010.html http • CWE-326: Inadequate Encryption Strength CWE-358: Improperly Implemented Security Check for Standard •
