CVSS: 7.5EPSS: 1%CPEs: 18EXPL: 0CVE-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 •
CVSS: 4.8EPSS: 0%CPEs: 41EXPL: 2CVE-2018-5407 – Intel (Skylake / Kaby Lake) - 'PortSmash' CPU SMT Side-Channel
https://notcve.org/view.php?id=CVE-2018-5407
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 •

https://notcve.org/view.php?id=CVE-2018-10392
mapping0_forward in mapping0.c in Xiph.Org libvorbis 1.3.6 does not validate the number of channels, which allows remote attackers to cause a denial of service (heap-based buffer overflow or over-read) or possibly have unspecified other impact via a crafted file. mapping0_forward en mapping0.c en Xiph.Org libvorbis 1.3.6 no valida el número de canales, lo que permite que atacantes remotos provoquen una denegación de servicio (desbordamiento o sobrelectura de búfer basada en memoria dinámica o heap) o provocar cualquier otro tipo de problema mediante un archivo manipulado. A heap-based buffer overflow was found in the encoder functionality of the libvorbis library. An attacker could create a malicious file to cause a denial of service, crashing the application containing the library. • https://access.redhat.com/errata/RHSA-2019:3703 https://gitlab.xiph.org/xiph/vorbis/issues/2335 https://lists.debian.org/debian-lts-announce/2019/11/msg00031.html https://lists.debian.org/debian-lts-announce/2021/11/msg00023.html https://security.gentoo.org/glsa/202003-36 https://access.redhat.com/security/cve/CVE-2018-10392 https://bugzilla.redhat.com/show_bug.cgi?id=1574193 • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
