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

The version of librabbitmq installed on the remote host is prior to 0.1-0.2.hgfb6fca832fd2.3. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1394 advisory.

 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update librabbitmq' to update your system.
