CVSS: 5.0EPSS: 92%CPEs: 25EXPL: 0CVE-2015-0206 – openssl: DTLS memory leak in dtls1_buffer_record
https://notcve.org/view.php?id=CVE-2015-0206
Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection. Fuga de memoria en la función dtls1_buffer_record en d1_pkt.c en OpenSSL 1.0.0 anterior a 1.0.0p y 1.0.1 anterior a 1.0.1k permite a atacantes remotos causar una denegación de servicio (consumo de memoria) mediante el envío de muchos archivos duplicados para la próxima época, lo que provoca un fallo de la detección de la reproducción. A memory leak flaw was found in the way the dtls1_buffer_record() function of OpenSSL parsed certain DTLS messages. A remote attacker could send multiple specially crafted DTLS messages to exhaust all available memory of a DTLS server. • http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147938.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/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00037.html http://marc.info/?l=bugtraq&m=142721102728110&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.0EPSS: 12%CPEs: 26EXPL: 1CVE-2014-3570 – openssl: Bignum squaring may produce incorrect results
https://notcve.org/view.php?id=CVE-2014-3570
The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c. La implementación BN_sqr en OpenSSL anterior a 0.9.8zd, 1.0.0 anterior a 1.0.0p, y 1.0.1 anterior a 1.0.1k no calcula correctamente el cuadrado de un valor BIGNUM, lo que podría facilitar a atacantes remotos superar los mecanismos de protección criptográficos a través de vectores no especificados, relacionado con crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, y crypto/bn/bn_asm.c. It was found that OpenSSL's BigNumber Squaring implementation could produce incorrect results under certain special conditions. This flaw could possibly affect certain OpenSSL library functionality, such as RSA blinding. Note that this issue occurred rarely and with a low probability, and there is currently no known way of exploiting it. • https://github.com/uthrasri/CVE-2014-3570 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/147938.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://lis • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2014-3571
OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c. OpenSSL anterior a 0.9.8zd, 1.0.0 anterior a 1.0.0p, y 1.0.1 anterior a 1.0.1k permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y caída de la aplicación) a través de un mensaje DTLS manipulado que se procesa con un operación diferente de lectura para la cabecera de negociación que la del cuerpo de la negociación, relacionado con la función dtls1_get_record en d1_pkt.c y la función ssl3_read_n en s3_pkt.c. A NULL pointer dereference flaw was found in the DTLS implementation of OpenSSL. A remote attacker could send a specially crafted DTLS message, which would cause an OpenSSL server to crash. • http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147938.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/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http://marc.info/?l=bugtraq&m=142496179803395&w •
CVSS: 5.0EPSS: 0%CPEs: 26EXPL: 0CVE-2014-3572 – openssl: ECDH downgrade bug fix
https://notcve.org/view.php?id=CVE-2014-3572
The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message. La función ssl3_get_key_exchange function en s3_clnt.c en OpenSSL en versiones anteriores a 0.9.8zd, 1.0.0 en versiones anteriores a 1.0.0p y 1.0.1 en versiones anteriores a 1.0.1k permite a servidores SSL remotos llevar a cabo ataques de desactualización ECDHE-to-ECDH y desencadenar una pérdida de confidencialidad directa omitiendo los mensajes ServerKeyExchange. It was discovered that OpenSSL would perform an ECDH key exchange with a non-ephemeral key even when the ephemeral ECDH cipher suite was selected. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method than the one requested by the user. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10679 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.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/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.h • CWE-310: Cryptographic Issues •

The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 0.9.8zc, 1.0.0o, and 1.0.1j does not properly handle attempts to use unsupported protocols, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an unexpected handshake, as demonstrated by an SSLv3 handshake to a no-ssl3 application with certain error handling. NOTE: this issue became relevant after the CVE-2014-3568 fix. La función ssl23_get_client_hello en s23_srvr.c en OpenSSL 0.9.8zc, 1.0.0o y 1.0.1j no maneja adecuadamente los intentos de utilizar protocolos no soportados, lo que permite a atacantes remotos causar una denegación de servicio (referencia a puntero NULL y caída de demonio) a través de un apretón de manos no esperado, según lo demostrado por un apretón de manos SSLv3 a una aplicación no-ssl3 con ciertos manejos de errores. NOTA: este problema se volvió relevante después de la corrección de CVE-2014-3568. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10679 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http://marc.info/?l=bugtraq&m=142496179803395&w=2 http://marc.info/?l=bugtraq&m=142496289803847&w=2 http://marc.info/?l=bug •
