CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2020-8252 – libuv: buffer overflow in realpath
https://notcve.org/view.php?id=CVE-2020-8252
The implementation of realpath in libuv < 10.22.1, < 12.18.4, and < 14.9.0 used within Node.js incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes. La implementación de realpath en libuv versiones anteriores a versiones anteriores a 10.22.1, versiones anteriores a 12.18.4 y versiones anteriores a 14.9.0, usada dentro de Node.js determinó incorrectamente el tamaño del búfer, lo que puede resultar en un desbordamiento del búfer si la ruta resuelta tiene más de 256 bytes A flaw has been found in libuv. The realpath() implementation performs an incorrect calculation when allocating a buffer, leading to a potential buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00023.html https://hackerone.com/reports/965914 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4OOYAMJVLLCLXDTHW3V5UXNULZBBK4O6 https://nodejs.org/en/blog/vulnerability/september-2020-security-releases https://security.gentoo.org/glsa/202009-15 https://security.netapp.com/advisory/ntap-20201009-0004 https://usn.ubuntu.com/4548- • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2020-8174
napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and < 14.4.0. La función napi_get_value_string_*(), permite varios tipos de corrupción de memoria en node versiones anteriores a 10.21.0, 12.18.0 y versiones anteriores a 14.4.0 A flaw was found in nodejs. Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer. • https://hackerone.com/reports/784186 https://security.gentoo.org/glsa/202101-07 https://security.netapp.com/advisory/ntap-20201023-0003 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2020-8174 https://bugzilla.redhat.com/show_bug.cgi?id=1845256 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-191: Integer Underflow (Wrap or Wraparound) •

https://notcve.org/view.php?id=CVE-2020-8172
TLS session reuse can lead to host certificate verification bypass in node version < 12.18.0 and < 14.4.0. La reutilización de una sesión TLS puede conllevar a una omisión de la verificación del certificado del host en node versión anterior a 12.18.0 y anterior a 14.4.0 A TLS Hostname verification bypass vulnerability exists in NodeJS. This flaw allows an attacker to bypass TLS Hostname verification when a TLS client reuses HTTPS sessions. • https://hackerone.com/reports/811502 https://nodejs.org/en/blog/vulnerability/june-2020-security-releases https://security.gentoo.org/glsa/202101-07 https://security.netapp.com/advisory/ntap-20200625-0002 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpujul2020.html https://www.oracle.com/security-alerts/cpuoct2020.html https://ac • CWE-285: Improper Authorization CWE-295: Improper Certificate Validation •
CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-11080 – Denial of service in nghttp2
https://notcve.org/view.php?id=CVE-2020-11080
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html https://github.com/nghttp2/nghttp2/commit/336a98feb0d56b9ac54e12736b18785c27f75090 https://github.com/nghttp2/nghttp2/commit/f8da73bd042f810f34d19f9eae02b46d870af394 https://github.com/nghttp2/nghttp2/security/advisories/GHSA-q5wr-xfw9-q7xr https://lists.debian.org/debian-lts-announce/2021/10/msg00011.html https://lists.debian.org/debian-lts-announce/2023/10/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject& • CWE-400: Uncontrolled Resource Consumption CWE-707: Improper Neutralization CWE-770: Allocation of Resources Without Limits or Throttling •
