CVSS: 5.9EPSS: 0%CPEs: 7EXPL: 0CVE-2016-7055 – openssl: Carry propagating bug in Montgomery multiplication
https://notcve.org/view.php?id=CVE-2016-7055
There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is because the subroutine in question is not used in operations with the private key itself and an input of the attacker's direct choice. Otherwise the bug can manifest itself as transient authentication and key negotiation failures or reproducible erroneous outcome of public-key operations with specially crafted input. Among EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation. • 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/cpuoct2017-3236626.html http://www.securityfocus.com/bid/94242 http://www.securitytracker.com/id/1037261 https://access.redhat.com/errata/RHSA-2018:2185 https://access.redhat.com/errata/RHSA-2018:2186 https://access.redhat.com/errata/RHSA-2018:2187 https://h20566.www2.hpe.com/hpsc/doc/public • CWE-682: Incorrect Calculation •

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 •

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-2016-2179
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 •

The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division results, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via unknown vectors.
