Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The amqp091-go library for Go, versions before 1.13.0, is vulnerable. A malicious or compromised AMQP server can send a message with an inflated body size, causing the client to attempt a huge memory allocation, which can exhaust system memory and crash the client process. No special privileges are needed beyond the server being able to deliver messages to the client. Upgrade to version 1.13.0 or later.
