Echo: at.yawk.lz4:lz4-java: security update to 1.11.2

medium Tenable Cloud Security Plugin ID 473997

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 1.11.2, net.jpountz.lz4.LZ4BlockInputStream
 refill() validates that the compressedLen field in a legacy LZ4Block header is nonnegative but allocates a
 compressed-input buffer of that attacker-controlled size before reading payload data, allowing a header-
 only stream to request a near-2 GiB allocation and exhaust the JVM heap. Canonical writers emit raw blocks
 when compression is not smaller than the original block, but vulnerable readers accept non-canonical
 oversized compressed blocks. This issue is fixed in version 1.11.2. (CVE-2026-106452)

Solution

Update the at.yawk.lz4:lz4-java library and its related packages to version 1.11.2 or later.
