    Package        : librabbitmq
    Version        : 0.10.0-1+deb11u3 0.11.0-1+deb12u3
    CVE ID         : CVE-2026-59986 CVE-2026-61547

    Two issues has been found in librabbitmq, AMQP client library and
    tools written in C.

    CVE-2026-59986

        The bounds check in librabbitmq/amqp_private.h function overflows
        causing out-of-bounds read on 32-bit systems which in turn causes
        information disclosure or denial of service.

    CVE-2026-61547

        A heap buffer overflow exists in rabbitmq-c when the public
        amqp_send_frame() API is used to serialize an oversized
        AMQP_FRAME_BODY. An application that passes an oversized body
        frame to amqp_send_frame() can trigger a heap out-of-bounds write,
        resulting in process crash and memory corruption.

    For Debian 11 bullseye, these problems have been fixed in version
    0.10.0-1+deb11u3.

    For Debian 12 bookworm, these problems have been fixed in version
    0.11.0-1+deb12u3.

    We recommend that you upgrade your librabbitmq packages.
