>                 URL: https://issues.apache.org/jira/browse/KAFKA-20043
>             Project: Kafka
>          Issue Type: Bug
>            Reporter: Jiyoung Lee
>            Priority: Major
>
> Kafka-clients references `lz4-java` that needs to be updated due to vulnerability issues
> `lz4-java` has to be 1.10.1 or higher to resolve the issue. 
> h2. yawkat LZ4 Java has a possible information leak in Java safe decompressor
> h2. Description
> Insufficient clearing of the output buffer in Java-based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data.
> JNI-based implementations are _not_ affected.
> h2. LZ4 Java Compression has Out-of-bounds memory operations which can cause DoS
> h2. Description
> Out-of-bounds memory operations in org.lz4:lz4-java 1.8.0 and earlier allow remote attackers to cause denial of service and read adjacent memory via untrusted compressed input.
> This is fixed in a forked release: at.yawk.lz4:lz4-java version 1.8.1. The original project has been archived: [https://github.com/lz4/lz4-java], and Sonatype has added a redirect from org.lz4:lz4-java:1.8.1 to the new group ID.
