CVSS: 5.9EPSS: 1%CPEs: 44EXPL: 0CVE-2016-0704 – openssl: SSLv2 Bleichenbacher protection overwrites wrong bytes for export ciphers
https://notcve.org/view.php?id=CVE-2016-0704
An oracle protection mechanism in the get_client_master_key function in s2_srvr.c in 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 overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a related issue to CVE-2016-0800. Un mecanismo de protección oracle en la función get_client_master_key en s2_srvr.c en la implementación de SSLv2 en OpenSSL en versiones anteriores a 0.9.8zf, 1.0.0 en versiones anteriores a 1.0.0r, 1.0.1 en versiones anteriores a 1.0.1m y 1.0.2 en versiones anteriores a 1.0.2a sobrescribe MASTER-KEY bytes incorrectos durante el uso de suites de cifrado de exportación, lo que facilita a atacantes remotos el descifrado de datos de texto cifrados con TLS aprovechándose de un Bleichenbacher RSA padding oracle, un caso relacionado con CVE-2016-0800. It was discovered that the SSLv2 protocol implementation in OpenSSL did not properly implement the Bleichenbacher protection for export cipher suites. An attacker could use a SSLv2 server using OpenSSL as a Bleichenbacher oracle. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00007.h • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2015-3195
The ASN1_TFLG_COMBINE implementation in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, and 1.0.2 before 1.0.2e mishandles errors caused by malformed X509_ATTRIBUTE data, which allows remote attackers to obtain sensitive information from process memory by triggering a decoding failure in a PKCS#7 or CMS application. La implementación ASN1_TFLG_COMBINE en crypto/asn1/tasn_dec.c en OpenSSL en versiones anteriores a 0.9.8zh, 1.0.0 en versiones anteriores a 1.0.0t, 1.0.1 en versiones anteriores a 1.0.1q y 1.0.2 en versiones anteriores a 1.0.2e no maneja correctamente los errores provocados por datos X509_ATTRIBUTE malformados, lo que permite a atacantes remotos obtener información sensible de memoria de proceso desencadenando un fallo de decodificación en una aplicación PKCS#7 o CMS. A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. • http://fortiguard.com/advisory/openssl-advisory-december-2015 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10733 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173801.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00009.html http://lists.opensuse& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •

La función PKCS7_dataDecode en crypto/pkcs7/pk7_doit.c en OpenSSL anterior a 0.9.8zg, 1.0.0 anterior a 1.0.0s, 1.0.1 anterior a 1.0.1n, y 1.0.2 anterior a 1.0.2b permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de aplicación) a través de un blob PKCS#7 que utiliza la codificación ASN.1 y al que le faltan datos EncryptedContent internos. A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. • http://fortiguard.com/advisory/openssl-vulnerabilities-june-2015 http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2015-008.txt.asc http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10694 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10733 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160436.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160647.html http& •

The dtls1_clear_queues function in ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h frees data structures without considering that application data can arrive between a ChangeCipherSpec message and a Finished message, which allows remote DTLS peers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unexpected application data. La función dtls1_clear_queues en ssl/d1_lib.c en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m, y 1.0.1 anterior a 1.0.1h libera estructuras de datos sin considerar que los datos de la aplicación puedan llegar entre un mensaje ChangeCipherSpec y un mensaje Finished, lo que permite a pares remotos de DTLS causar una denegación de servicio (corrupción de memoria y caída de aplicación) o posiblemente tener otro impacto no especificado a través de datos de la aplicación no esperados. An invalid-free flaw was found in the way OpenSSL handled certain DTLS handshake messages.
