CVE-2015-5143 – Django: possible DoS by filling session store
https://notcve.org/view.php?id=CVE-2015-5143
The session backends in Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (session store consumption) via multiple requests with unique session keys. La sesión Backend en Django anteriores a 1.4.21, de 1.5.x hasta 1.6.x, 1.7.x anteriores a 1.7.9 y 1.8.x anteriores a 1.8.3, permite a un atacante causar una denegación de servicios mediante el consumo de almacenamiento de sesión a través de múltiples peticiones con una única clave de sesión. A flaw was found in the Django session backend, which could allow an unauthenticated attacker to create session records in the configured session store, causing a denial of service by filling up the session store. • http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172084.html http://lists.opensuse.org/opensuse-updates/2015-10/msg00043.html http://lists.opensuse.org/opensuse-updates/2015-10/msg00046.html http://rhn.redhat.com/errata/RHSA-2015-1678.html http://rhn.redhat.com/errata/RHSA-2015-1686.html http://www.debian.org/security/2015/dsa-3305 http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.securityfocus.com/bid/75666 http://www.s • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVE-2015-1819 – libxml2: denial of service processing a crafted XML document
https://notcve.org/view.php?id=CVE-2015-1819
The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack. Vulnerabilidad en el xmlreader en libxml, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de datos XML manipulados, relacionada con un ataque XML Entity Expansión (XEE). A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00000.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00001.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00002.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172710.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172943.html http://lists.opensuse.org/opensuse-updates/2015- • CWE-399: Resource Management Errors •
CVE-2015-2730 – NSS: ECDSA signature validation fails to handle some signatures correctly (MFSA 2015-64)
https://notcve.org/view.php?id=CVE-2015-2730
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. Under certain conditions, an attacker could use this flaw to conduct signature forgery attacks. • 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-2015-1664.html http://rhn.redhat.com/errata/RHSA-2015-1699.html http://www.debian.org • CWE-310: Cryptographic Issues CWE-347: Improper Verification of Cryptographic Signature •
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 •
