https://notcve.org/view.php?id=CVE-2016-6304
Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2 before 1.0.2i, and 1.1.0 before 1.1.0a allow remote attackers to cause a denial of service (memory consumption) via large OCSP Status Request extensions. Múltiples fugas de memoria en t1_lib.c en OpenSSL en versiones anteriores a 1.0.1u, 1.0.2 en versiones anteriores a 1.0.2i y 1.1.0 en versiones anteriores a 1.1.0a permiten a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de grandes extensiones OCSP Status Request A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. Double-free and invalid-free vulnerabilities in x509 parsing were found in the latest OpenSSL (1.1.0b). • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2016-6306
The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before 1.0.2i might allow remote attackers to cause a denial of service (out-of-bounds read) via crafted certificate operations, related to s3_clnt.c and s3_srvr.c. El analizador certificado en OpenSSL en versiones anteriores a 1.0.1u y 1.0.2 en versiones anteriores a 1.0.2i podría permitir a atacantes remotos provocar una denegación de servicio (lectura fuera de rango) a través de operaciones certificadas manipuladas, relacionado con s3_clnt.c y s3_srvr.c. Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2016-2179
The DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries associated with unused out-of-order messages, which allows remote attackers to cause a denial of service (memory consumption) by maintaining many crafted DTLS sessions simultaneously, related to d1_lib.c, statem_dtls.c, statem_lib.c, and statem_srvr.c. La implementación DTLS en OpenSSL en versiones anteriores a 1.1.0 no restringe adecuadamente la vida útil de entradas de cola asociadas con mensajes fuera de servicio no usados, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) manteniendo muchas sesiones DTLS manipuladas simultáneamente, relacionado con d1_lib.c, statem_dtls.c, statem_lib.c y statem_srvr.c. It was discovered that the Datagram TLS (DTLS) implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://rhn.redhat.com/errata/RHSA-2016-1940.html http://www-01.ibm.com/support/docview.wss?uid=swg21995039 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/cpujul2017-3236622.html http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html http://www.oracle.com/technetwork& • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
