Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to an infinite loop in the run-length encoding RLE state machine within the Bzip2Decoder handler when processing a malformed bzip2 stream, which allows an attacker to exploit the issue by sending a specially crafted bzip2 stre...

Infinite loop

Overview io.netty:netty-codec is an event-driven asynchronous network application framework. Affected versions of this package are vulnerable to Infinite loop in the Bzip2Decoder handler's run-length encoding state machine. An attacker can cause the event-loop thread to hang indefinitely by...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the Bzip2Decoder handler's run-length encoding state machine. An attacker can cause the event-loop thread to hang indefinitely by supplying a specially crafted bzip2 stream that triggers an infinite loop during...

GHSA-558V-64GR-WGG4 Netty: [Bzip2Decoder] Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

The Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the event-loop thread in an infinite loop. The vulnerability exists in the run-length encoding RLE state machine within...
