Frequently Asked Questions

1

What input path must be exposed for this issue to be exploitable?

An application must process untrusted compressed input using org.lz4:lz4-java. Remote attackers can use that input to trigger denial of service or potentially read adjacent memory.

2

Which lz4-java versions are affected?

Version 1.8.0 and earlier are affected.

3

How can I determine whether my application may be exposed?

Check Maven dependencies, including transitive dependencies, for org.lz4:lz4-java at version 1.8.0 or earlier. Then identify whether the application decompresses data supplied by remote or otherwise untrusted sources.

4

What should be prioritized if patching cannot happen immediately?

Prioritize preventing untrusted compressed input from reaching lz4-java decompression paths, especially in remotely accessible services. The provided information does not specify an alternative mitigation.
