CVE-2025-66217

AIS-catcher is a multi-platform AIS receiver. Prior to version 0.64, an integer underflow vulnerability exists in the MQTT parsing logic of AIS-catcher. This vulnerability allows an attacker to trigger a massive Heap Buffer Overflow by sending a malformed MQTT packet with a manipulated Topic Length field. This leads to an immediate Denial of Service (DoS) and, when used as a library, severe Memory Corruption that can be leveraged for Remote Code Execution (RCE). This issue has been patched in version 0.64.

Summary		(es) AIS-catcher es un receptor AIS multiplataforma. Antes de la versión 0.64, existe una vulnerabilidad de desbordamiento negativo de enteros en la lógica de análisis MQTT de AIS-catcher. Esta vulnerabilidad permite a un atacante activar un desbordamiento de búfer de montón masivo enviando un paquete MQTT malformado con un campo Topic Length manipulado. Esto conduce a una denegación de servicio (DoS) inmediata y, cuando se usa como una biblioteca, a una corrupción de memoria grave que puede ser aprovechada para ejecución remota de código (RCE). Este problema ha sido parcheado en la versión 0.64.
