CVSS: 4.3EPSS: 0%CPEs: 24EXPL: 1CVE-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 •
CVSS: 5.1EPSS: 0%CPEs: 25EXPL: 0CVE-2013-1620 – nss: TLS CBC padding timing attack
https://notcve.org/view.php?id=CVE-2013-1620
The TLS implementation in Mozilla Network Security Services (NSS) does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169. La implementación en Mozilla Network Security Services (NSS) de TLS no tiene debidamente en cuenta tiempos de canal lateral ataques a una operación de comprobación de incumplimiento MAC durante el procesamiento de malformaciones relleno CBC, que permite a atacantes remotos para realizar ataques distintivos y los ataques de recuperación de texto plano-a través de análisis estadístico de datos de tiempo de los paquetes hechos a mano, una cuestión relacionada con CVE-2013-0169. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.opensuse.org/opensuse-security-announce/2013-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2013-04/msg00010.html http://openwall.com/lists/oss-security/2013/02/05/24 http://rhn.redhat.com/errata/RHSA-2013-1135.html http://rhn.redhat.com/errata/RHSA-2013-1144.html http://seclists.org/fulldisclosure/2014/Dec/23 http://security.gentoo.org/glsa/glsa-201406-19.xml http://www. • CWE-203: Observable Discrepancy •
