CVSS: 5.3EPSS: 2%CPEs: 102EXPL: 0CVE-2017-3735 – openssl: Malformed X.509 IPAdressFamily could cause OOB read
https://notcve.org/view.php?id=CVE-2017-3735
While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread. This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. Al analizar una extensión IPAddressFamily en un certificado X.509, es posible realizar una sobrelectura de un bit. Esto tendría como resultado que el texto del certificado se muestre de forma incorrecta. • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/100515 http://www.securitytracker.com/id/1039726 https://access.redhat.com/errata/RHSA-2018:3221 https://access.redhat.com/errata/RHSA-2018:3505 https://cert-portal.siem • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

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 •

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 •
