SCA: security update for at.yawk.lz4:lz4-java (GHSA-xx22-p4ch-683r)

medium Tenable Cloud Security Plugin ID 445288

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.1, JNI-backed XXHash implementations fail
 to validate the byte array object and the off and len arguments in
 XXHashFactory.nativeInstance().hash32().hash(), XXHashFactory.nativeInstance().hash64().hash(),
 XXHashFactory.nativeInstance().newStreamingHash32().update(), and
 XXHashFactory.nativeInstance().newStreamingHash64().update(), allowing null arrays or oversized ranges to
 reach native code, read outside the Java array, and fatally terminate the JVM. This issue is fixed in
 version 1.11.1. (CVE-2026-59949)

Solution

Update the at.yawk.lz4:lz4-java library and its related packages to version 1.11.1 or later.
