CVSS: 7.5EPSS: 27%CPEs: 87EXPL: 1CVE-2016-8610 – SSL/TLS: Malformed plain-text ALERT packets could cause remote DoS
https://notcve.org/view.php?id=CVE-2016-8610
A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. Se ha encontrado un fallo de denegación de servicio en OpenSSL en las versiones 0.9.8, 1.0.1, 1.0.2 hasta la 1.0.2h y la 1.1.0 en la forma en la que el protocolo TLS/SSL definió el procesamiento de paquetes ALERT durante una negociación de conexión. Un atacante remoto podría emplear este fallo para hacer que un servidor TLS/SSL consuma una cantidad excesiva de recursos de CPU y fracase a la hora de aceptar conexiones de otros clientes. A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. • https://github.com/cujanovic/CVE-2016-8610-PoC http://rhn.redhat.com/errata/RHSA-2017-0286.html http://rhn.redhat.com/errata/RHSA-2017-0574.html http://rhn.redhat.com/errata/RHSA-2017-1415.html http://rhn.redhat.com/errata/RHSA-2017-1659.html http://seclists.org/oss-sec/2016/q4/224 http://www.securityfocus.com/bid/93841 http://www.securitytracker.com/id/1037084 https://access.redhat.com/errata/RHSA-2017:1413 https://access.redhat.com/errata/RHSA-2017:1414 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 45EXPL: 1CVE-2016-2183 – CVE-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 •

The X509_NAME_oneline function in crypto/x509/x509_obj.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to obtain sensitive information from process stack memory or cause a denial of service (buffer over-read) via crafted EBCDIC ASN.1 data. La función X509_NAME_oneline en crypto/x509/x509_obj.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 obtener información sensible de la pila de memoria de proceso o provocar una denegación de servicio (sobrelectura de buffer) a través de datos EBCDIC ASN.1 manipulados. • http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://packetstormsecurity.com/files/136912/Slackware-Security-Advisory-openssl-Updates.html http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160504-openssl http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html http://www.oracle.com/technetwork/topics& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 33%CPEs: 23EXPL: 0CVE-2016-2106 – openssl: EVP_EncryptUpdate overflow
https://notcve.org/view.php?id=CVE-2016-2106
Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.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 data. Desbordamiento de entero en la función EVP_EncryptUpdate en crypto/evp/evp_enc.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. An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncryptUpdate() 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-189: Numeric Errors •
