CVSS: 7.1EPSS: 91%CPEs: 34EXPL: 0CVE-2014-3567 – openssl: Invalid TLS/SSL session tickets could cause memory leak leading to server crash
https://notcve.org/view.php?id=CVE-2014-3567
Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure. Fuga de memoria en la función tls_decrypt_ticket en t1_lib.c en OpenSSL anterior a 0.9.8zc, 1.0.0 anterior a 1.0.0o, y 1.0.1 anterior a 1.0.1j permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de un ticket de sesión manipulado que provoca un fallo en la comprobación de integridad. A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-015.txt.asc http://advisories.mageia.org/MGASA-2014-0416.html http://aix.software.ibm.com/aix/efixes/security/openssl_advisory11.asc http://lists.apple.com/archives/security-announce/2015/Jan/msg00003.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2014-11/msg00001.html http& • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2014-0224
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability. OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h no restringe debidamente el procesamiento de mensajes ChangeCipherSpec, lo que permite a atacantes man-in-the-middle provocar el uso de una clave maestra de longitud cero en ciertas comunicaciones OpenSSL-a-OpenSSL, y como consecuencia secuestrar sesiones u obtener información sensible, a través de una negociación TLS manipulada, también conocido como la vulnerabilidad de 'inyección CCS'. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. • https://github.com/secretnonempty/CVE-2014-0224 https://github.com/iph0n3/CVE-2014-0224 http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://ccsinjection.lepidum.co.jp http://dev.mysql.com/doc/relnotes/workbench/en/wb-news-6-1-7.html http://esupport.trendmicro.com/solution/en-US/1103813.aspx http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://kb.juniper.net/InfoCenter/ • CWE-326: Inadequate Encryption Strength CWE-841: Improper Enforcement of Behavioral Workflow •

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 •

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 •
