CVE-2026-39304

Опубликовано: 10 апр. 2026
Источник: redhat
CVSS3: 7.5

Описание

A flaw was found in Apache ActiveMQ Client, Apache ActiveMQ Broker, and Apache ActiveMQ. A remote attacker can exploit this vulnerability by rapidly triggering Transport Layer Security (TLS) version 1.3 handshake KeyUpdates. This improper handling of KeyUpdates causes the broker to exhaust its memory in the SSL engine, leading to a Denial of Service (DoS) condition where the service becomes unavailable.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Denial of Service via Out of Memory vulnerability in Apache ActiveMQ Client, Apache ActiveMQ Broker, Apache ActiveMQ. ActiveMQ NIO SSL transports do not correctly handle TLSv1.3 handshake KeyUpdates triggered by clients. This makes it possible for a client to rapidly trigger updates which causes the broker to exhaust all its memory in the SSL engine leading to DoS. Note: TLS versions before TLSv1.3 (such as TLSv1.2) are broken but are not vulnerable to OOM. Previous TLS versions require a full handshake renegotiation which causes a connection to hang but not OOM. This is fixed as well. This issue affects Apache ActiveMQ Client: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.4; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.4. Users are recommended to upgrade to version 6.2.4 or 5.19.5, which fixes the issue.
