SCA: security update for org.apache.activemq:activemq-client, org.apache.activemq:activemq-openwire-legacy (GHSA-whxr-3p84-rf3c)

medium Tenable Cloud Security Plugin ID 428436

Description

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

 - Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ. During unmarshalling of
 OpenWire commands the size value of buffers was not properly validated which could lead to excessive
 memory allocation and be exploited to cause a denial of service (DoS) by depleting process memory, thereby
 affecting applications and services that rely on the availability of the ActiveMQ broker when not using
 mutual TLS connections. This issue affects Apache ActiveMQ: from 6.0.0 before 6.1.6, from 5.18.0 before
 5.18.7, from 5.17.0 before 5.17.7, before 5.16.8. ActiveMQ 5.19.0 is not affected. Users are recommended
 to upgrade to version 6.1.6+, 5.19.0+, 5.18.7+, 5.17.7, or 5.16.8 or which fixes the issue. Existing users
 may implement mutual TLS to mitigate the risk on affected brokers. (CVE-2025-27533)
