CVE-2019-5737 – nodejs: Insufficient Slowloris fix causing DoS via server.headersTimeout bypass
https://notcve.org/view.php?id=CVE-2019-5737
In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1. En Node.js, que incluye la versión 6.x en versiones anteriores a la 6.17.0, 8.x en versiones anteriores a la 8.15.1, 10.x en versiones anteriores a la 10.15.2 y 11.x en versiones anteriores a la 11.10.1, un atacante puede provocar una denegación de servicio (DoS) instalando una conexión HTTP o HTTPS en modo keep-alive y enviando encabezados muy lentamente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00059.html https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/february-2019-security-releases https://security.gentoo.org/glsa/202003-48 https://security.netapp.com/advisory/ntap-20190502-0008 https://access.redhat.com/security/cve/CVE-2019-5737 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
CVE-2018-12122 – nodejs: Slowloris HTTP Denial of Service

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Slowloris HTTP Denial of Service: An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. 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) HTTP mediante Slowloris. Un atacante puede provocar una denegación de servicio (DoS) enviando cabeceras muy lentamente, manteniendo las conexiones HTTP o HTTPS y los recursos asociados vivos durante un largo período de tiempo. It was found that Node.js HTTP server was vulnerable to a Slowloris type attack. An attacker could make long lived connections by sending bytes very slowly to the server, saturating its resource and possibly resulting in a denial of service. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12122 https://bugzilla.redhat.com/show_bug.cgi?id=1661005 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-12123 – nodejs: Hostname spoofing in URL parser for javascript protocol

Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Hostname spoofing in URL parser for javascript protocol: If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

Si una aplicación de Node.js está empleando url.parse() para determinar el nombre de host de la URL, dicho nombre puede suplantarse mediante un protocolo "javascript:" de letra mixta (por ejemplo, "javAscript:"). • https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12123 https://bugzilla.redhat.com/show_bug.cgi?id=1661010 • CWE-20: Improper Input Validation CWE-115: Misinterpretation of Input •
CVE-2018-12121 – nodejs: Denial of Service with large HTTP headers
https://notcve.org/view.php?id=CVE-2018-12121
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 •
