CVE-2025-14935

NSF Unidata NetCDF-C Dimension Name Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NSF Unidata NetCDF-C. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of dimension names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27168.

Summary		(es) Vulnerabilidad de ejecución remota de código por desbordamiento de búfer basado en montículo en el nombre de dimensión de NSF Unidata NetCDF-C. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de NSF Unidata NetCDF-C. Se requiere interacción del usuario para explotar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. El fallo específico existe en el análisis de los nombres de dimensión. El problema se debe a la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer basado en montículo de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. Era ZDI-CAN-27168.
