{"id":"UBUNTU-CVE-2026-79921","details":"amqp091-go is a Go AMQP 0.9.1 client. Before version 1.13.0, a compromised or malicious AMQP broker can force the client to allocate resources for and process content body frames that exceed the negotiated frame_max limit. This can lead to unexpected memory consumption or application-layer denial of service (DoS), bypassing the protocol's built-in framing constraints. Version 1.13.0 contains a fix. No known workarounds are available.","modified":"2026-09-02T19:42:23.577412067Z","published":"2026-08-26T21:16:00Z","upstream":["CVE-2026-79921"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-79921"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-79921"},{"type":"REPORT","url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-6c5v-hqjr-5xxp"},{"type":"REPORT","url":"https://github.com/rabbitmq/amqp091-go/pull/353"}],"affected":[{"package":{"name":"golang-github-rabbitmq-amqp091-go","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-rabbitmq-amqp091-go?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-2","1.9.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rabbitmq-amqp091-go-dev","binary_version":"1.9.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-79921.json"}},{"package":{"name":"golang-github-rabbitmq-amqp091-go","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-rabbitmq-amqp091-go?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-rabbitmq-amqp091-go-dev","binary_version":"1.10.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-79921.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H"},{"type":"Ubuntu","score":"medium"}]}
