CVE-2025-14932

Full vulnerability record from the local CVENow database.

Description

NSF Unidata NetCDF-C Time Unit 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 time units. 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-27273.

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 en el análisis de las unidades de tiempo. 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 pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. Fue ZDI-CAN-27273."
