CVE-2025-5318
Estado: ModificadaAlta (8.1)—
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.

"value": "A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior."

Una lectura fuera de los límites puede activarse en la función sftp_handle debido a una comprobación de comparación incorrecta que permite que la función acceda a memoria más allá de la lista de manejadores válidos y devuelva un puntero no válido, que se utiliza en el procesamiento posterior. Esta vulnerabilidad permite que un atacante remoto autenticado lea regiones de memoria no deseadas, exponiendo información confidencial o afectando el comportamiento del servicio."
