CVE-2017-5645 – log4j: Socket receiver deserialization vulnerability
https://notcve.org/view.php?id=CVE-2017-5645
In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. En Apache Log4j 2.x en versiones anteriores a 2.8.2, cuando se utiliza el servidor de socket TCP o el servidor de socket UDP para recibir sucesos de registro serializados de otra aplicación, puede enviarse una carga binaria especialmente diseñada que, cuando se deserializa, puede ejecutar código arbitrario. It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. • https://github.com/pimps/CVE-2017-5645 http://www.openwall.com/lists/oss-security/2019/12/19/2 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/97702 http://www.securitytracker.com/id/1040200 http://www.securit • CWE-502: Deserialization of Untrusted Data •
CVE-2015-7940 – bouncycastle: Invalid curve attack allowing to extract private keys
https://notcve.org/view.php?id=CVE-2015-7940
The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman (ECDH) key exchanges, aka an "invalid curve attack." La librería Bouncy Castle Java en versiones anteriores a 1.51 no valida un punto que se encuentra dentro de la curva elíptica, lo que facilita a atacantes remotos obtener claves privadas a través de una serie de intercambios de clave de curva elíptica Diffie Hellman (ECDH) manipulados, también conocida como un 'ataque de curva no válida'. It was found that bouncycastle is vulnerable to an invalid curve attack. An attacker could extract private keys used in elliptic curve cryptography with a few thousand queries. • http://lists.fedoraproject.org/pipermail/package-announce/2016-January/174915.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00012.html http://rhn.redhat.com/errata/RHSA-2016-2035.html http://rhn.redhat.com/errata/RHSA-2016-2036.html http://web-in-security.blogspot.ca/2015/09/practical-invalid-curve-attacks.html http://www.debian.org/security/2015/dsa-3417 http://www.openwall.com/lists/oss-security/2015/10/22/7 http://www.openwall.com/lists/oss-security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues CWE-358: Improperly Implemented Security Check for Standard •
