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 •

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 •

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.

The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before 1.0.2i might allow remote attackers to cause a denial of service (out-of-bounds read) via crafted certificate operations, related to s3_clnt.c and s3_srvr.c. El analizador certificado en OpenSSL en versiones anteriores a 1.0.1u y 1.0.2 en versiones anteriores a 1.0.2i podría permitir a atacantes remotos provocar una denegación de servicio (lectura fuera de rango) a través de operaciones certificadas manipuladas, relacionado con s3_clnt.c y s3_srvr.c. Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL. • 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-125: Out-of-bounds Read •

Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2 before 1.0.2i, and 1.1.0 before 1.1.0a allow remote attackers to cause a denial of service (memory consumption) via large OCSP Status Request extensions.
