A flaw was found in iperf3. A remote attacker can exploit this vulnerability by sending crafted control-channel JSON with oversized numeric parameters, such as `parallel` and `len`, which are not properly validated by the server. This improper input validation can lead to excessive stream and thread creation, as well as large buffer allocations, causing resource exhaustion. Consequently, this can …

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the JSON utility parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth for arrays or objects. As a result, a small but deeply nested, syntactically valid FHIR JSON document can trigger unbounded readArray() or readObject() recursion, raising …

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner() and parseElement(), raising a StackOverflowError. An attacker who can submit FHIR resources containing such narratives can t…

Socket.IO enables bidirectional and low-latency communication for every platform. Prior to 4.2.7, 3.4.5, and 3.3.6, a specially crafted Socket.IO packet can make the server wait for a large number of binary attachments and buffer them, which can be exploited to make the server run out of memory. This vulnerability is fixed in 4.2.7, 3.4.5, and 3.3.6.

Better Auth relies on better-call, which uses the rou3 router library. In affected versions of rou3, paths are normalized by removing empty segments, so /path, //path, and ///path resolve to the same route. In Better Auth versions prior to 1.4.5 (which bundles the fixed rou3), this can allow attackers to bypass disabledPaths configuration and path-based rate limits by submitting requests with extr…

Vulnerabilidad alta en GitPython anterior a 3.1.50 permite inyección de código remoto

GitPython versiones anteriores a 3.1.50 no valida correctamente caracteres de salto de línea en el parámetro section de config_writer(), permitiendo a atacantes inyectar encabezados arbitrarios en .git/config. Los adversarios pueden manipular la sección [core] para dirigir hooksPath hacia directorios controlados, logrando ejecución de código remoto cuando se activan hooks de Git. Esta vulnerabilidad afecta principalmente a repositorios compartidos y entornos de integración continua en empresas de México y Latinoamérica.

Vulnerabilidad de denegación de servicio en FreeRDP anterior a versión 3.29.0

FreeRDP versiones anteriores a 3.29.0 contiene una vulnerabilidad de denegación de servicio (DoS) en el manejador del canal RDPEI que no valida la longitud máxima del cuerpo PDU antes de asignar memoria. Un cliente RDP malicioso puede enviar un mensaje RDPEI solo con encabezado y una longitud de cuerpo declarada grande, forzando asignación excesiva de memoria en el servidor. Empresas en LATAM que utilizan FreeRDP en infraestructuras de acceso remoto deben actualizar inmediatamente para evitar interrupciones de servicios altas.
