Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment. Condición de carrera en la función ssl3_read_bytes en s3_pkt.c en OpenSSL hasta 1.0.1g, cuando SSL_MODE_RELEASE_BUFFERS está habilitado, permite a atacantes remotos inyectar datos a través de sesiones o causar una denegación de servicio (error de uso después de liberación y análisis sintáctico) a través de una conexión SSL en un entorno con múltiples hilos. • http://advisories.mageia.org/MGASA-2014-0187.html http://ftp.openbsd.org/pub/OpenBSD/patches/5.5/common/004_openssl.patch.sig http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00016.html http:/& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 7.5EPSS: 97%CPEs: 54EXPL: 16CVE-2014-0160 – OpenSSL Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2014-0160
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Las implementaciones de (1) TLS y (2) DTLS en OpenSSL 1.0.1 en versiones anteriores a 1.0.1g no manejan adecuadamente paquetes Heartbeat Extension, lo que permite a atacantes remotos obtener información sensible desde la memoria de proceso a través de paquetes manipulados que desencadenan una sobrelectura del buffer, según lo demostrado mediante la lectura de claves privadas, relacionado con d1_both.c y t1_lib.c, también conocido como bug Heartbleed. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. • https://www.exploit-db.com/exploits/32764 https://www.exploit-db.com/exploits/32791 https://www.exploit-db.com/exploits/32998 https://www.exploit-db.com/exploits/32745 https://github.com/0x90/CVE-2014-0160 https://github.com/jdauphant/patch-openssl-CVE-2014-0160 https://github.com/caiqiqi/OpenSSL-HeartBleed-CVE-2014-0160-PoC https://github.com/obayesshelton/CVE-2014-0160-Scanner https://github.com/MrE-Fog/CVE-2014-0160-Chrome-Plugin https://github.com/Xyl2k/CVE-2014&# • CWE-125: Out-of-bounds Read CWE-201: Insertion of Sensitive Information Into Sent Data •

The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack. La implementación de la escala Montgomery en OpenSSL hasta la versión 1.0.0l no asegura que ciertas operaciones de intercambio tengan un comportamiento constante en el tiempo, lo que facilita a usuarios locales obtener nonces ECDSA a través de un ataque de caché de canal lateral FLUSH+RELOAD. • http://advisories.mageia.org/MGASA-2014-0165.html http://eprint.iacr.org/2014/140 http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=2198be3483259de374f91e57d247d0fc667aef29 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00011.html http://lists.opensuse.org/opensuse-updates/2014-04/msg00007.html http://marc.info/?l=bugtraq&m=140266410314613&w=2 http://marc.info/?l=bugtraq&m=140317760000786&w=2 http&# • CWE-310: Cryptographic Issues •

The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c. La implementación de retransmisión DTLS en OpenSSL través 0.9.8y y 1.x través 1.0.1e no mantiene adecuadamente las estructuras de datos para sumarios (hashes) y contextos de cifrado, lo que podría permitir a atacantes man-in-the-middle para activar el uso de un contexto diferente e interferir con la entrega de paquetes, relacionado con ssl/d1_both.c y ssl/t1_enc.c. • http://git.openssl.org/gitweb/?p=openssl.git%3Ba=commit%3Bh=34628967f1e65dc8f34e000f0f5518e21afbfc7b http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136470.html http://lists.fedoraproject.org/pipermail/package-announce/2014-August/136473.html http://lists.opensuse.org/opensuse-updates/2014-01/msg00031.html http://lists.opensuse.org/opensuse-updates/2014-01/msg00032.html http://rhn.redhat.com/errata/RHSA-2014-0015.html http://seclists.org/fulldisclosure/2014/Dec/23 http://security. • CWE-310: Cryptographic Issues •
