https://notcve.org/view.php?id=CVE-2020-13935
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. La longitud de la carga útil en una trama de WebSocket no fue comprobada correctamente en Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M6, versiones 9.0.0.M1 hasta 9.0.36, versiones 8.5.0 hasta 8.5.56 y versiones 7.0.27 hasta 7.0. 104. Las longitudes de carga útil no válidas podrían desencadenar un bucle infinito. • https://github.com/RedTeamPentesting/CVE-2020-13935 https://github.com/aabbcc19191/CVE-2020-13935 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00084.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00088.html https://kc.mcafee.com/corporate/index?page=content&id=SB10332 https://lists.apache.org/thread.html/r4e5d3c09f4dd2923191e972408b40fb8b42dbff0bc7904d44b651e50%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/rd48c72bd3255bda87564d4da3791517c074d94f8a701f93b85752651%40%3Cannounce& • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux. libldap en determinados paquetes OpenLDAP de terceros presenta un fallo de comprobación de certificados cuando el paquete de terceros está afirmando que admite RFC6125.

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) •

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.

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 •
