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 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.
