Echo: librabbitmq: security update to 0.15.0-1+deb13u1

medium Tenable Cloud Security Plugin ID 455188

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can
send an undersized HEADER or METHOD frame during client login and cause unsigned size_t underflow in
amqp_handle_input() in librabbitmq/amqp_connection.c. The parser subtracts HEADER_SIZE, fixed per-frame
fields, and FOOTER_SIZE from state->target_size without first checking the minimum frame length. The
wrapped encoded.len value is passed through amqp_decode_properties() to amqp_decode_table_internal(),
where it defeats bounds checks and causes an out-of-bounds read and process crash. An on-path attacker can
also trigger the issue when AMQP traffic is not protected by TLS with certificate validation. The
demonstrated impact is denial of service, with no reliable memory disclosure or code execution shown. This
issue is fixed in version 0.16.0. (CVE-2026-44235)

Solution

Update the librabbitmq library and its related packages to version 0.15.0-1+deb13u1 or later.
