Overview

io.netty:netty-codec is an event-driven asynchronous network application framework.

Affected versions of this package are vulnerable to Denial of Service (DoS). SnappyFrameDecoder doesn't restrict chunk length any mad buffer skippable chunks in an unnecessary way, leading to excessive memory usage. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file), or by sending a huge skippable chunk.

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

  • High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

  • Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

Remediation

Upgrade io.netty:netty-codec to version 4.1.68.Final or higher.

Overview

io.netty:netty-codec is an event-driven asynchronous network application framework.

Affected versions of this package are vulnerable to Denial of Service (DoS). Bzip2Decoder doesn't allow setting size restrictions for decompressed data. An attacker can exploit this by providing a compressed file that, when decompressed, triggers an out-of-memory exception.

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

  • Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package
