Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer. Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Denegación de servicio (DoS) con cabeceras HTTP grandes. Mediante la combinación de muchas peticiones con cabeceras de tamaño máximo (casi 80 KB por conexión) y al terminar a su debido tiempo las cabeceras, es posible provocar que el servidor HTTP aborte el fallo de asignación de memoria dinámica (heap). El potencial del ataque se ve mitigado por el uso de un balance de carga u otra capa del proxy. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://access.redhat.com/errata/RHSA-2019:2258 https://access.redhat.com/errata/RHSA-2019:3497 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12121 https://bugzilla.redhat.com/show_bug.cgi?id=1661002 • CWE-400: Uncontrolled Resource Consumption •

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105758 https://access.redhat.com/errata/RHSA-2019:2304 https://access.redhat.com/errata/RHSA-2019:3700 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://git.openssl.org/gitweb/?p=openssl.git%3Ba • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-385: Covert Timing Channel •

The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Se ha demostrado que el algoritmo de firmas ECDSA en OpenSSL es vulnerable a un ataque de sincronización de canal lateral. • http://www.securityfocus.com/bid/105750 http://www.securitytracker.com/id/1041986 https://access.redhat.com/errata/RHSA-2019:3700 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=56fb454d281a023b3f950d969693553d3f3ceea1 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=b1d6d55ece1c26fa2829e2b819b038d7b6d692b4 https://lists.debian.org/debian-lts-announce/2018/11/msg00024.html https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.netapp.com/advisor • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-385: Covert Timing Channel •
