CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2018-7161 – nodejs: denial of service (DoS) by causing a node server providing an http2 server to crash
https://notcve.org/view.php?id=CVE-2018-7161
All versions of Node.js 8.x, 9.x, and 10.x are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation. Todas las versiones 8.x, 9.x y 10.x de Node.js son vulnerables y la gravedad es ALTA. • http://www.securityfocus.com/bid/106363 https://nodejs.org/en/blog/vulnerability/june-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-7161 https://bugzilla.redhat.com/show_bug.cgi?id=1591013 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2018-7162
All versions of Node.js 9.x and 10.x are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node process which provides an http server supporting TLS server to crash. This can be accomplished by sending duplicate/unexpected messages during the handshake. This vulnerability has been addressed by updating the TLS implementation.

CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2018-7167 – nodejs: Denial of Service by calling Buffer.fill() or Buffer.alloc() with specially crafted parameters
https://notcve.org/view.php?id=CVE-2018-7167
Calling Buffer.fill() or Buffer.alloc() with some parameters can lead to a hang which could result in a Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc() and Buffer.fill() were updated so that they zero fill instead of hanging in these cases. All versions of Node.js 6.x (LTS "Boron"), 8.x (LTS "Carbon"), and 9.x are vulnerable. All versions of Node.js 10.x (Current) are NOT vulnerable. La llamada a Buffer.fill() o Buffer.alloc() con algunos parámetros puede conducir a un bloqueo y a una denegación de servicio (DoS) posterior. • http://www.securityfocus.com/bid/106363 https://nodejs.org/en/blog/vulnerability/june-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-7167 https://bugzilla.redhat.com/show_bug.cgi?id=1591006 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 4%CPEs: 13EXPL: 0CVE-2018-0732 – Client DoS due to large DH parameter
https://notcve.org/view.php?id=CVE-2018-0732
During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o). • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/104442 http://www.securitytracker.com/id/1041090 https://access.redhat.com/errata/RHSA-2018:2552 https://access.redhat.com/errata/RHSA-2018:2553 https://access.redhat.com/errata/RHSA-2018:3221 https://access.redhat.com/errata/RHSA-2018:3505 https://access.redhat.com/errata/RHSA-2019:1296 https://access.redhat.com/errata/RHSA-2019:1297 https://access.redhat.com/errata/ • CWE-320: Key Management Errors CWE-325: Missing Cryptographic Step •
CVSS: 5.3EPSS: 0%CPEs: 7EXPL: 0CVE-2018-7159 – nodejs: HTTP parser allowed for spaces inside Content-Length header values
https://notcve.org/view.php?id=CVE-2018-7159
The HTTP parser in all current versions of Node.js ignores spaces in the `Content-Length` header, allowing input such as `Content-Length: 1 2` to be interpreted as having a value of `12`. The HTTP specification does not allow for spaces in the `Content-Length` value and the Node.js HTTP parser has been brought into line on this particular difference. The security risk of this flaw to Node.js users is considered to be VERY LOW as it is difficult, and may be impossible, to craft an attack that makes use of this flaw in a way that could not already be achieved by supplying an incorrect value for `Content-Length`. Vulnerabilities may exist in user-code that make incorrect assumptions about the potential accuracy of this value compared to the actual length of the data supplied. Node.js users crafting lower-level HTTP utilities are advised to re-check the length of any input supplied after parsing is complete. • https://access.redhat.com/errata/RHSA-2019:2258 https://nodejs.org/en/blog/vulnerability/march-2018-security-releases https://support.f5.com/csp/article/K27228191?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-7159 https://bugzilla.redhat.com/show_bug.cgi?id=1561981 • CWE-20: Improper Input Validation CWE-115: Misinterpretation of Input •
