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

medium Tenable Self-Hosted Container Security Plugin ID 473993

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.LZ4FrameInputStream
 readHeader() allocates two new 4 MiB block buffers whenever a maximum-block-size frame header is read, and
 the default concatenated-frame mode allows attacker-controlled streams containing many minimal empty
 frames to trigger roughly 8 MiB of allocation for every 11 input bytes. The stream produces no
 decompressed output while consuming CPU and garbage-collection time, so decompressed-size limits do not
 mitigate the issue; readSingleFrame mode is not affected. This issue is fixed in version 1.11.4.
 (CVE-2026-106450)

Solution

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