CVE-2025-14933

NSF Unidata NetCDF-C NC Variable Integer 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 NC variables. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27266.

Summary		(es) Vulnerabilidad de desbordamiento de entero en variable NC de NSF Unidata NetCDF-C con ejecución remota de código (RCE). 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.\n\nEl fallo específico existe dentro del análisis de variables NC. El problema se debe a la falta de validación adecuada de los datos suministrados por el usuario, lo que puede provocar un desbordamiento de entero antes de asignar un búfer. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. Fue ZDI-CAN-27266.
