CVE-2018-0734 – Timing attack against DSA
https://notcve.org/view.php?id=CVE-2018-0734
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 •
CVE-2018-12115 – nodejs: Out of bounds (OOB) write via UCS-2 encoding
https://notcve.org/view.php?id=CVE-2018-12115
In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written. En todas las versiones de Node.js anteriores a la 6.14.4, 8.11.4 y 10.9.0, cuando se utiliza con codificación UCS-2 (reconocida por Node.js bajo los nombres "ucs2", "ucs-2", "utf16le" y "utf-16le"), se puede explotar "Buffer#write()" para escribir fuera de los límites de un búfer. Las escrituras que empiezan desde la segunda hasta la última posición de un búfer provocan un error de cálculo de la longitud máxima de los bytes de entrada que se van a escribir. • http://www.securityfocus.com/bid/105127 https://access.redhat.com/errata/RHSA-2018:2552 https://access.redhat.com/errata/RHSA-2018:2553 https://access.redhat.com/errata/RHSA-2018:2944 https://access.redhat.com/errata/RHSA-2018:2949 https://access.redhat.com/errata/RHSA-2018:3537 https://nodejs.org/en/blog/vulnerability/august-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12115 https://bugzilla.redhat.com • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-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 •
CVE-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') •
CVE-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 •
