Unknown · Ais-Catcher · CVE-2025-66217
**Name of the Vulnerable Software and Affected Versions**
AIS-catcher versions prior to 0.64
**Description**
AIS-catcher, a multi-platform AIS receiver, contains a flaw in its MQTT parsing logic. An integer underflow can be triggered by sending a crafted MQTT packet with a modified Topic Length field. This can cause a significant Heap Buffer Overflow, resulting in a Denial of Service (DoS). When used as a library, this can also lead to severe Memory Corruption, potentially enabling Remote Code Execution (RCE). The issue is related to the parsing of the `Topic Length` field within MQTT packets.
**Recommendations**
Update to version 0.64 or later.
