FreeBSD : rabbitmq-c -- multiple vulnerabilities (03308f12-c15d-11f1-ab87-107c611e671e)

high Nessus Plugin ID 363458

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 03308f12-c15d-11f1-ab87-107c611e671e advisory.

The rabbitmq-c project reports:
CVE-2026-44236: A malicious AMQP server can send an undersized connection.tune.frame_max value during the login handshake. The library does not enforce the protocol minimum frame size, reallocates its outbound buffer to an invalid size and then writes frame data beyond it, causing a heap buffer overflow before authentication completes.
CVE-2026-44235: An unsigned integer underflow in the frame length computation when parsing undersized AMQP frames bypasses bounds checks in the property and table decoders, leading to an out-of-bounds read and client-side denial of service.

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

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

Solution

Update the affected packages.
