CVE-2025-14936

NSF Unidata NetCDF-C Attribute Name Stack-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 attribute 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 stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27269.

Summary		(es) Vulnerabilidad de desbordamiento de búfer basado en pila y ejecución remota de código en nombres de atributos 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.\n\nEl defecto específico existe dentro del análisis de nombres de atributos. El problema resulta de la falta de validación adecuada de la longitud de los datos suministrados por el usuario antes de copiarlos a un búfer de longitud fija basado en pila. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. Fue ZDI-CAN-27269.
