The sigalgs implementation in t1_lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by using an invalid signature_algorithms extension in the ClientHello message during a renegotiation. La implementación sigalgs en t1_lib.c en OpenSSL 1.0.2 anterior a 1.0.2a permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída del demonio) mediante el uso de una extensión signature_algorithms inválida en el mensaje ClientHello durante una renegociación. • http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://marc.info/?l=bugtraq&m=144050297101809&w=2 http://www.fortiguard.com/advisory/2015-03-24-openssl-vulnerabilities-march-2015 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.oracle.com/technetwork/topics/security/bulletinapr2015-2511959.html http://www.oracle.com/technetwork/topics/security/cpujan2016-2367955.html http://www.oracle.com/technetwork/ •
CVSS: 7.5EPSS: 18%CPEs: 22EXPL: 1CVE-2015-0292 – openssl: integer underflow leading to buffer overflow in base64 decoding
https://notcve.org/view.php?id=CVE-2015-0292
Integer underflow in the EVP_DecodeUpdate function in crypto/evp/encode.c in the base64-decoding implementation in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted base64 data that triggers a buffer overflow. Subdesbordamiento de enteros en la función EVP_DecodeUpdate en crypto/evp/encode.c en la implementación base64-decoding en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m, y 1.0.1 anterior a 1.0.1h permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado a través de datos base64 manipulados que provocan un desbordamiento de buffer. An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input (such as a PEM file) could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://marc.info/?l=bugtraq&m=143213830203296&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.inf • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message. La implementación SSLv2 en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a permite a atacantes remotos causar una denegación de servicio (fallo de aserción s2_lib.c y salida del demonio) a través de un mensaje CLIENT-MASTER-KEY manipulado. A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/156823.html http://lists.fedoraproject.org/pipermail/package-announce/ • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •

The ssl3_get_client_key_exchange function in s3_srvr.c in OpenSSL 1.0.2 before 1.0.2a, when client authentication and an ephemeral Diffie-Hellman ciphersuite are enabled, allows remote attackers to cause a denial of service (daemon crash) via a ClientKeyExchange message with a length of zero. La función ssl3_get_client_key_exchange en s3_srvr.c en OpenSSL 1.0.2 anterior a 1.0.2a, cuando la autenticación del cliente y un suite de cifrado Diffie-Hellman efímero están habilitados, permite a atacantes remotos causar una denegación de servicio (caída del demonio) a través de un mensaje ClientKeyExchange con una longitud de cero. • http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.info/?l=bugtraq&m=144050155601375&w=2 http://marc.info/?l=bugtraq&m=144050297101809&w=2 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.oracle.com/technetwork/topics/security/bulletinapr2015-2511959.html http://www.oracle.com/technetwork/topics/security/cpujan2016-2367955.html http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html http://www.oracle.com/technetwork/topics/s • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-8275
OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c. OpenSSL anterior a 0.9.8zd, 1.0.0 anterior a 1.0.0p, y 1.0.1 anterior a 1.0.1k no fuerza ciertas limitaciones sobre datos de certificados, lo que permite a atacantes remotos derrotar un mecanismo de protección de lista negra de certificados basado en huellas dactilares mediante la inclusión de datos manipulados dentro de la porción no firmada de un certificado, relacionado con crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, y crypto/x509/x_all.c. Multiple flaws were found in the way OpenSSL parsed X.509 certificates. An attacker could use these flaws to modify an X.509 certificate to produce a certificate with a different fingerprint without invalidating its signature, and possibly bypass fingerprint-based blacklisting in applications. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10679 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148363.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00 • CWE-310: Cryptographic Issues •
