How to Fix GHSA-q4h9-7rxj-7gx2

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.lettuce:lettuce-core fixed: 6.5.1.RELEASE 
<dependency>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
    <version>6.5.1.RELEASE</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.lettuce

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-q4h9-7rxj-7gx2, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.lettuce

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.5.1.RELEASE), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.lettuce command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Source Advisory Statement

# Withdrawn Advisory This advisory has been withdrawn because users of Lettuce may independently exclude vulnerable versions of Netty from their dependencies, and those users should not receive alerts for CVE-2024-47535. This link is maintained to preserve external references. # Original Description ### Summary Note: i'm reporting this in this way purely because it's private and i don't want to broadcast vulnerabilities. > An unsafe reading of environment file could potentially cause a denial of service in Netty. When loaded on an Windows application, Netty attempts to load a file that does not exist. If an attacker creates such a large file, the Netty application crashes. This vulnerability is fixed in 4.1.115. ### Details https://github.com/redis/lettuce/blob/main/pom.xml#L67C9-L67C53 The netty version pinned here is currently ``` <netty.version>4.1.113.Final</netty.version> ``` This version is vulnerable according to Snyk and is affecting one of our products: ![image](https://github.com/user-attachments/assets/a7c78c24-f1e3-4f29-bc49-b252d330002a) Here is a [link](https://www.cve.org/CVERecord?id=CVE-2024-47535) to the CVE ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ Not applicable ### Impact _What kind of vulnerability is it?
