Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'. SMT (Simultaneous Multi-threading) en los procesadores puede habilitar que usuarios locales exploten software vulnerable a ataques de sincronización mediante un ataques de sincronización de canal lateral en la "contención de puertos". A microprocessor side-channel vulnerability was found on SMT (e.g, Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process can extract certain secret information. • https://www.exploit-db.com/exploits/45785 http://www.securityfocus.com/bid/105897 https://access.redhat.com/errata/RHSA-2019:0483 https://access.redhat.com/errata/RHSA-2019:0651 https://access.redhat.com/errata/RHSA-2019:0652 https://access.redhat.com/errata/RHSA-2019:2125 https://access.redhat.com/errata/RHSA-2019:3929 https://access.redhat.com/errata/RHSA-2019:3931 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

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).

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 •

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 •
