CVSS: 5.9EPSS: 0%CPEs: 34EXPL: 0CVE-2017-3738 – openssl: rsaz_1024_mul_avx2 overflow bug on x86_64
https://notcve.org/view.php?id=CVE-2017-3738
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. 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 DH1024 are considered just feasible, 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 significant. • 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/102118 http://www.securitytracker.com/id/1039978 https://access.redhat.com/errata/RHSA-2018:0998 https://access.redhat.com/errata/RHSA-2018:2185 https://access.redhat.co • CWE-190: Integer Overflow or Wraparound CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Node.js before 4.8.5, 6.x before 6.11.5, and 8.x before 8.8.0 allows remote attackers to cause a denial of service (uncaught exception and crash) by leveraging a change in the zlib module 1.2.9 making 8 an invalid value for the windowBits parameter. Node.js en versiones anteriores a la 4.8.5, las versiones 6.x anteriores a la 6.11.5 y las versiones 8.x anteriores a la 8.8.0 permiten que atacantes remotos provoquen una denegación de servicio (excepción no detectada y cierre inesperado) aprovechando un cambio en el módulo zlib, versión 1.2.9, que hace que 8 sea un valor no válido para el parámetro windowsBits. • http://www.securityfocus.com/bid/101881 https://nodejs.org/en/blog/release/v4.8.5 https://nodejs.org/en/blog/release/v6.11.5 https://nodejs.org/en/blog/release/v8.8.0 https://nodejs.org/en/blog/vulnerability/oct-2017-dos • CWE-20: Improper Input Validation •
CVSS: 7.5EPSS: 0%CPEs: 100EXPL: 0CVE-2017-11499 – nodejs: Constant Hashtable Seeds vulnerability
https://notcve.org/view.php?id=CVE-2017-11499
Node.js v4.0 through v4.8.3, all versions of v5.x, v6.0 through v6.11.0, v7.0 through v7.10.0, and v8.0 through v8.1.3 was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup. Node.js versión v4.0 hasta v4.8.3, todas las versiones de v5.x, versión v6.0 hasta v6.11.0, versión v7.0 hasta v7.10.0, y versión v8.0 hasta v8.1.3, fue susceptible a ataques DoS remotos de inundación de hash ya que el seed HashTable fue constante en una versión dada de Node.js. Esto fue el resultado de la compilación con instantáneas V8 habilitadas por defecto, lo que causó que el seed aleatorizado inicialmente se sobrescribiera en el arranque. It was found that Node.js was using a non-randomized seed when populating hash tables. • http://www.securityfocus.com/bid/99959 https://access.redhat.com/errata/RHSA-2017:2908 https://access.redhat.com/errata/RHSA-2017:3002 https://nodejs.org/en/blog/vulnerability/july-2017-security-releases https://access.redhat.com/security/cve/CVE-2017-11499 https://bugzilla.redhat.com/show_bug.cgi?id=1475327 • CWE-20: Improper Input Validation •

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 •
