The UpdateHub firmware-update agent's probe handler (z_impl_updatehub_probe() in subsys/mgmt/updatehub/updatehub.c) parses the JSON metadata returned by the update server into a fixed two-level nested-array struct. After parsing it validates only the outer array length (objects_len != 2) and then dereferences objects[1].objects[0].objects.sha256sum via strlen() without checking that the inner obje…

Vulnerabilidad alta de denegación de servicio en FastSchema v0.15.1 permite caída del servidor

Una vulnerabilidad de desreferencia de puntero NULL en FastSchema hasta la versión 0.15.1 permite que atacantes no autenticados derriben el servidor con una única solicitud HTTP. El defecto se encuentra en la función sendOTPEmail (pkg/auth/local.go) que procesa solicitudes de recuperación de contraseña sin validar correctamente el manejo de errores, causando un pánico fatal que interrumpe toda la aplicación. Afecta particularmente a empresas en LATAM que usan FastSchema en entornos de producción para autenticación de usuarios.

Vulnerabilidad alta en Klever-Go causa denegación de servicio en nodos blockchain

Klever-Go versiones 1.7.14 a 1.7.17 son vulnerables a un pánico por null-pointer desencadenado cuando una transacción protobuf omite el sub-mensaje RawData incrustado. Un atacante puede enviar transacciones malformadas a través de la red P2P de Klever-Go para causar caída inmediata de nodos validadores. Esto afecta principalmente a operadores de nodos blockchain, exchanges cripto y plataformas DeFi en México y LATAM que ejecuten estas versiones.

NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 have a command execution vulnerability due to unsafe use of `shell=True` with commands that rely on executable resolution through the `PATH` environment variable. An attacker controlling the execution environment can place malicious executables such as sudo ea…

In open62541 v1.5.5, the server-side AddReferences implementation contains an incomplete validation flaw for non-local ExpandedNodeId targets. A remote attacker can send a crafted AddReferencesRequest with an empty targetServerUri and a non-zero targetNodeId.serverIndex, causing the target node pointer to remain NULL while execution continues.

Vulnerabilidad alta de desreferencia nula en FreeRDP 3.28.x y anteriores

FreeRDP versiones anteriores a 3.29.0 contiene una vulnerabilidad de desreferencia de puntero nulo en el manejo de solicitudes de control de dispositivos smartcard. Un atacante puede enviar peticiones IRP malformadas con datos de estado de lector truncados para causar el bloqueo del proceso. Esta vulnerabilidad afecta servidores de acceso remoto y clientes RDP en infraestructuras de LATAM que dependen de autenticación por tarjeta inteligente.

NULL Pointer Dereference vulnerability in Apache NimBLE in LE Long Term Key Request event. This requires disabled asserts (otherwise assert would trigger before NULL dereference) and bogus (or misbehaving) controller, thus severity is low. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.
