A timing attack flaw was found in OpenSSL 1.0.1u and before that could allow a malicious user with local access to recover ECDSA P-256 private keys. Se ha encontrado un error de ataque de sincronización en OpenSSL, en versiones 1.0.1u y anteriores, que podría permitir que un usuario malicioso con acceso local recupere claves privadas ECDSA P-256 A timing attack flaw was found in OpenSSL that could allow a malicious user with local access to recover ECDSA P-256 private keys. • http://rhn.redhat.com/errata/RHSA-2017-1415.html http://www.securityfocus.com/bid/95375 http://www.securitytracker.com/id/1037575 https://access.redhat.com/errata/RHSA-2017:1413 https://access.redhat.com/errata/RHSA-2017:1414 https://access.redhat.com/errata/RHSA-2017:1801 https://access.redhat.com/errata/RHSA-2017:1802 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-7056 https://eprint.iacr.org/2016/1195 https://ftp.openbsd.org/pub/OpenBSD/patches/5.9/ • CWE-320: Key Management Errors CWE-385: Covert Timing Channel •
CVSS: 7.5EPSS: 0%CPEs: 45EXPL: 1CVE-2016-2183 – SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)
https://notcve.org/view.php?id=CVE-2016-2183
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack. Los cifrados DES y Triple DES, como se usan en los protocolos TLS, SSH e IPSec y otros protocolos y productos, tienen una cota de cumpleaños de aproximadamente cuatro mil millones de bloques, lo que facilita a atacantes remotos obtener datos de texto plano a través de un ataque de cumpleaños contra una sesión cifrada de larga duración, según lo demostrado por una sesión HTTPS usando Triple DES en modo CBC, también conocido como un ataque "Sweet32". A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. IBM Informix Dynamic Server suffers from dll injection, PHP code injection, and heap buffer overflow vulnerabilities. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 7.5EPSS: 8%CPEs: 61EXPL: 0CVE-2016-2105 – openssl: EVP_EncodeUpdate overflow
https://notcve.org/view.php?id=CVE-2016-2105
Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of binary data. Desbordamiento de entero en la función EVP_EncodeUpdate en crypto/evp/encode.c en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria dinámica) a través de una gran cantidad de datos binarios. An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncodeUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-05/ • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
CVSS: 10.0EPSS: 90%CPEs: 40EXPL: 0CVE-2016-2108 – openssl: Memory corruption in the ASN.1 encoder
https://notcve.org/view.php?id=CVE-2016-2108
The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the "negative zero" issue. La implementación ASN.1 en OpenSSL en versiones anteriores a 1.0.1o y 1.0.2 en versiones anteriores a 1.0.2c permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento inferior de buffer y corrupción de memoria) a través de un campo ANY en datos serializados manipulados, también conocido como el problema "cero negativo". A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-05/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
