Summary
A denial-of-service vulnerability in kafka-python before version 2.3.2 allows a malicious broker or man-in-the-middle attacker to exhaust memory or hang connections. The attack sends a crafted 4-byte frame length value without bounds validation.
Risk Assessment
The attack can crash applications using kafka-python, causing service disruptions and requiring consumer restarts.
Recommendation
Update kafka-python to version 2.3.2 or later, which includes the frame length validation fix.
Other vulnerabilities in kafka-python
Original NVD description (English source)
kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in the protocol parser that allows a malicious broker or machine-in-the-middle attacker to exhaust memory or hang connections by sending a crafted 4-byte frame length value without bounds validation. Attackers can send a specially crafted frame length through the receive_bytes() function to trigger either a multi-gigabyte memory allocation or an uncaught ValueError that leaves the connection in a broken state, causing requests to hang and consumers to stop heartbeating until restart.
