CVE-2016-7798
https://notcve.org/view.php?id=CVE-2016-7798
The openssl gem for Ruby uses the same initialization vector (IV) in GCM Mode (aes-*-gcm) when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism. La openssl gem para Ruby utiliza el mismo vector de inicialización (IV) en el modo GCM (aes - * - gcm) cuando el IV se establece en versiones anteriores a la clave, lo que facilita que los atacantes dependiendo del contexto eludan el mecanismo de protección del cifrado. • http://www.openwall.com/lists/oss-security/2016/09/19/9 http://www.openwall.com/lists/oss-security/2016/09/30/6 http://www.openwall.com/lists/oss-security/2016/10/01/2 http://www.securityfocus.com/bid/93031 https://github.com/ruby/openssl/commit/8108e0a6db133f3375608303fdd2083eb5115062 https://github.com/ruby/openssl/issues/49 https://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://www.debian.org/security/2017/dsa-3966 • CWE-326: Inadequate Encryption Strength •

CVE-2000-1254
https://notcve.org/view.php?id=CVE-2000-1254
crypto/rsa/rsa_gen.c in OpenSSL before 0.9.6 mishandles C bitwise-shift operations that exceed the size of an expression, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging improper RSA key generation on 64-bit HP-UX platforms. crypto/rsa/rsa_gen.c en OpenSSL en versiones anteriores a 0.9.6 maneja incorrectamente operaciones de desplazamiento a nivel de bit en C que exceden el tamaño de una expresión, lo que facilita a atacantes remotos vencer mecanismos de protección criptográfica aprovechando la generación incorrecta de claves RSA sobre plataformas HP-UX de 64-bit. • http://marc.info/?l=openssl-users&m=95961024500509 http://www-01.ibm.com/support/docview.wss?uid=swg21995039 http://www.openwall.com/lists/oss-security/2016/05/04/17 http://www.securityfocus.com/bid/90109 http://www.securitytracker.com/id/1035750 https://git.openssl.org/?p=openssl.git%3Ba=commit%3Bh=db82b8f9bd432a59aea8e1014694e15fc457c2bb • CWE-310: Cryptographic Issues •
CVE-2016-2176

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 •
CVE-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 •
