How to Fix CVE-2024-36124

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

org.iq80.snappy:snappy fixed: 0.5 
<dependency>
    <groupId>org.iq80.snappy</groupId>
    <artifactId>snappy</artifactId>
    <version>0.5</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=org.iq80.snappy

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-36124, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.iq80.snappy

Analyze the terminal output to locate any version of Snappy in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.iq80.snappy 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Snappy, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary iq80 Snappy performs out-of-bounds read access when uncompressing certain data, which can lead to a JVM crash. ### Details When uncompressing certain data, Snappy tries to read outside the bounds of the given byte arrays. Because Snappy uses the JDK class `sun.misc.Unsafe` to speed up memory access, no additional bounds checks are performed and this has similar security consequences as out-of-bounds access in C or C++, namely it can lead to non-deterministic behavior or crash the JVM. iq80 Snappy is not actively maintained anymore. As quick fix users can upgrade to version 0.5, but in the long term users should prefer migrating to the Snappy implementation in https://github.com/airlift/aircompressor (version 0.27 or newer). ### Impact When uncompressing data from untrusted users, this can be exploited for a denial-of-service attack by crashing the JVM.
