Echo: at.yawk.lz4:lz4-java: security update to 1.11.4

low Tenable Cloud Security Plugin ID 474009

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 1.11.4, net.jpountz.lz4.LZ4BlockInputStream
 configured with stopOnEmptyBlock set to false handles each well-formed empty LZ4Block by recursively
 calling refill(), allowing a long sequence of empty blocks in an attacker-controlled compressed stream to
 exhaust the decoding thread's stack and throw StackOverflowError. The default stopOnEmptyBlock setting is
 true and is not affected, and the issue does not cause memory corruption. This issue is fixed in version
 1.11.4. (CVE-2026-106449)

Solution

Update the at.yawk.lz4:lz4-java library and its related packages to version 1.11.4 or later.
