Amazon Linux AMI : librabbitmq (ALAS-2020-1394)

critical Nessus Plugin ID 138636

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.
(CVE-2019-18609)

Solution

Run 'yum update librabbitmq' to update your system.
