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 •

CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2018-7166 – nodejs: Unintentional exposure of uninitialized memory
https://notcve.org/view.php?id=CVE-2018-7166
In all versions of Node.js 10 prior to 10.9.0, an argument processing flaw can cause `Buffer.alloc()` to return uninitialized memory. This method is intended to be safe and only return initialized, or cleared, memory. The third argument specifying `encoding` can be passed as a number, this is misinterpreted by `Buffer's` internal "fill" method as the `start` to a fill operation. This flaw may be abused where `Buffer.alloc()` arguments are derived from user input to return uncleared memory blocks that may contain sensitive information. En todas las versiones de Node.js 10 anteriores a la 10.9.0, un fallo en el procesamiento de argumentos puede provocar que "Buffer.alloc()" devuelva memoria no inicializada. • https://access.redhat.com/errata/RHSA-2018:2553 https://nodejs.org/en/blog/vulnerability/august-2018-security-releases https://access.redhat.com/security/cve/CVE-2018-7166 https://bugzilla.redhat.com/show_bug.cgi?id=1620215 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-226: Sensitive Information in Resource Not Removed Before Reuse CWE-908: Use of Uninitialized Resource •
CVSS: 8.1EPSS: 1%CPEs: 4EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2018-7164
Node.js versions 9.7.0 and later and 10.x are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour. Todas las versiones 9.7.0 y posteriores y 10.x de Node.js son vulnerables y la gravedad es MEDIA. • http://www.securityfocus.com/bid/104463 https://nodejs.org/en/blog/vulnerability/june-2018-security-releases https://security.gentoo.org/glsa/202003-48 • CWE-400: Uncontrolled Resource Consumption •
