io.netty : netty-codec : 4.1.52.Final sonatype-2021-0789
The netty-codec package contains a Buffer Overflow vulnerability. The finishEncode function in the Lz4FrameEncoder.class class incorrectly estimates the buffer size when writing a footer for the last header. An attacker could abuse this behavior by sending a payload to the flawed application that will overwrite contiguous memory chunks in the heap, resulting in a Denial of Service (DoS) condition or other unintended behavior.
The application is vulnerable by using this component.
We recommend upgrading to a version of this component that is not vulnerable to this specific issue.
Note: If this component is included as a bundled/transitive dependency of another component, there may not be an upgrade path. In this instance, we recommend contacting the maintainers who included the vulnerable package. Alternatively, we recommend investigating alternative components or a potential mitigating control.
