CVE-2025-14934

NSF Unidata NetCDF-C Variable 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 variable 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-27267.

Summary		(es) Vulnerabilidad de desbordamiento de búfer basado en pila y ejecución remota de código (RCE) en nombres de variables 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 problema específico existe dentro del análisis de los nombres de variables. El problema se debe a 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-27267.
