A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230929-0006 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-1206 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2023-2422
A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. Se encontró una falla en Keycloak.

https://notcve.org/view.php?id=CVE-2023-2585
Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client. La concesión de autorización del dispositivo de Keycloak no valida correctamente el código del dispositivo y la identificación del cliente. Un cliente atacante podría abusar de la validación faltante para falsificar una solicitud de consentimiento del cliente y engañar a un administrador de autorización para que otorgue el consentimiento a un cliente OAuth malicioso o un posible acceso no autorizado a un cliente OAuth existente. • https://access.redhat.com/errata/RHSA-2023:3883 https://access.redhat.com/errata/RHSA-2023:3884 https://access.redhat.com/errata/RHSA-2023:3885 https://access.redhat.com/errata/RHSA-2023:3888 https://access.redhat.com/errata/RHSA-2023:3892 https://access.redhat.com/security/cve/CVE-2023-2585 https://bugzilla.redhat.com/show_bug.cgi?id=2196335 • CWE-358: Improperly Implemented Security Check for Standard •
