CVSS: 5.9EPSS: 0%CPEs: 21EXPL: 0CVE-2017-3732 – BN_mod_exp may produce incorrect results on x86_64
https://notcve.org/view.php?id=CVE-2017-3732
There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. • 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/95814 http://www.securitytracker.com/id/1037717 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://access.redhat.com/errata/RHSA-2018:2 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.5EPSS: 4%CPEs: 22EXPL: 0CVE-2017-3731 – Truncated packet could crash via OOB read
https://notcve.org/view.php?id=CVE-2017-3731
If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to 1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k. Si un servidor o cliente SSL/TLS se ejecuta en un host de 32 bits y se utiliza un cifrador específico, un paquete truncado puede dar lugar a que el servidor o el cliente realicen una lectura fuera de límites que, normalmente, provoca un cierre inesperado En OpenSSL 1.1.0, el cierre inesperado se puede desencadenar cuando se usa CHACHA20/POLY1305 An integer underflow leading to an out of bounds read flaw was found in OpenSSL. A remote attacker could possibly use this flaw to crash a 32-bit TLS/SSL server or client using OpenSSL if it used the RC4-MD5 cipher suite. • http://rhn.redhat.com/errata/RHSA-2017-0286.html http://www.debian.org/security/2017/dsa-3773 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/95813 http://www.securitytracker.com/id/1037717 https://access.redhat.com/errata/RHSA-2018:2185 https://access.redhat.com/errata/RHSA-2018 • CWE-125: Out-of-bounds Read •
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-2016-6304
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 •
