https://notcve.org/view.php?id=CVE-2016-1978
Use-after-free vulnerability in the ssl3_HandleECDHServerKeyExchange function in Mozilla Network Security Services (NSS) before 3.21, as used in Mozilla Firefox before 44.0, allows remote attackers to cause a denial of service or possibly have unspecified other impact by making an SSL (1) DHE or (2) ECDHE handshake at a time of high memory consumption. Vulnerabilidad de uso después de liberación de memoria en la función ssl3_HandleECDHServerKeyExchange en Mozilla Network Security Services (NSS) en versiones anteriores a 3.21, como se utiliza en Mozilla Firefox en versiones anteriores a 44.0, permite a atacantes remotos causar una denegación de servicio o posiblemente tener otro impacto no especificado llevando a cabo un apretón de manos SSL (1) DHE o (2) ECDHE en un momento de alto consumo de memoria. A use-after-free flaw was found in the way NSS handled DHE (Diffie–Hellman key exchange) and ECDHE (Elliptic Curve Diffie-Hellman key exchange) handshake messages. A remote attacker could send a specially crafted handshake message that, when parsed by an application linked against NSS, would cause that application to crash or, under certain special conditions, execute arbitrary code using the permissions of the user running the application. • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00093.html http://rhn.redhat.com/errata/RHSA-2016-0591.html http://rhn.redhat.com/errata/RHSA-2016-0684.html http://rhn.redhat.com/errata/RHSA-2016-0685.html http://www.debian.org/security/2016/dsa- •

Use-after-free vulnerability in the PK11_ImportDERPrivateKeyInfoAndReturnKey function in Mozilla Network Security Services (NSS) before 3.21.1, as used in Mozilla Firefox before 45.0, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted key data with DER encoding. Vulnerabilidad de uso después de liberación de memoria en la función PK11_ImportDERPrivateKeyInfoAndReturnKey en Mozilla Network Security Services (NSS) en versiones anteriores a 3.21.1, como se utiliza en Mozilla Firefox en versiones anteriores a 45.0, permite a atacantes remotos causar una denegación de servicio o posiblemente tener otro impacto no especificado a través de datos de clave manipulados con codificado DER. A use-after-free flaw was found in the way NSS processed certain DER (Distinguished Encoding Rules) encoded cryptographic keys. An attacker could use this flaw to create a specially crafted DER encoded certificate which, when parsed by an application compiled against the NSS library, could cause that application to crash, or execute arbitrary code using the permissions of the user running the application. • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00093.html http://rhn.redhat.com/errata/RHSA-2016-0591.html http:&# •

https://notcve.org/view.php?id=CVE-2015-7575
Mozilla Network Security Services (NSS) before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof servers by triggering a collision. Mozilla Network Security Services (NSS) en versiones anteriores a 3.20.2, tal como se utiliza en Mozilla Firefox en versiones anteriores a 43.0.2 y Firefox ESR 38.x en versiones anteriores a 38.5.2, no rechaza las firmas MD5 en mensajes Server Key Exchange en el tráfico de TLS 1.2 Handshake Protocol, lo que facilita a atacantes man-in-the-middle falsificar servidores desencadenando una colisión. A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client. • http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-01 • CWE-19: Data Processing Errors •
