{"id":"UBUNTU-CVE-2026-69219","details":"The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.1, src/main/java/com/rabbitmq/client/impl/ValueReader.java uses ValueReader.readBytes to accept a wire-declared contentLength below Integer.MAX_VALUE and allocate a byte array before checking the bytes available in the frame. A malicious AMQP peer can send a LongString or byte-array field with type tag S and a declared length such as 0x7FFFFFFE during the pre-authentication connection.start server-properties table, causing an approximately 2 GB allocation and OutOfMemoryError before readFully consumes data. The resulting memory exhaustion can terminate the JVM and cause denial of service. This issue is fixed in version 5.33.1.","modified":"2026-09-02T19:36:28.354301486Z","published":"2026-08-18T17:17:00Z","upstream":["CVE-2026-69219"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-69219"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-69219"}],"affected":[{"package":{"name":"rabbitmq-java-client","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-java-client?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librabbitmq-client-java","binary_version":"5.0.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69219.json"}},{"package":{"name":"rabbitmq-java-client","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-java-client?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librabbitmq-client-java","binary_version":"5.0.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69219.json"}},{"package":{"name":"rabbitmq-java-client","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-java-client?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.0.0-1.1","binary_name":"librabbitmq-client-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69219.json"}},{"package":{"name":"rabbitmq-java-client","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-java-client?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.0.0-1.1","binary_name":"librabbitmq-client-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69219.json"}},{"package":{"name":"rabbitmq-java-client","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rabbitmq-java-client?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.0-1.1","5.0.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"5.0.0-2","binary_name":"librabbitmq-client-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-69219.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
