NVD Description

Note: Versions mentioned in the description apply only to the upstream guac package and not the guac package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
