CyberRota Analysis
AI-GeneratedThe python-socketio server prior to version 5.16.4 is vulnerable to a memory retention issue where an attacker can exploit the system by sending incomplete binary messages, leading to potential denial-of-service conditions due to excessive memory usage. This vulnerability poses a significant risk to applications using python-socketio for real-time communication, particularly those that handle untrusted client connections. Organizations utilizing this library should prioritize upgrading to version 5.16.4 or later to mitigate the risk of memory exhaustion attacks.

Original NVD Description
python-socketio is a Python implementation of the Socket.IO realtime client and server. The python-socketio server stores binary `EVENT` and `ACK` messages in memory while it waits to receive their binary attachments. Once all the attachments are received, these messages are then processed. Prior to version 5.16.4, an attacker can submit a binary message and intentionally omit sending one or more of its attachments to cause the message along with the partial list of received attachments to stay in memory for a long time. Version 5.16.4 takes the following measures to address this issue: Binary packets are only accepted from authenticated clients and, when a client disconnects, the server checks if there is a partial binary message being held for the client and deletes it.
