    Package        : librabbitmq
    Version        : 0.10.0-1+deb11u2 0.11.0-1+deb12u2
    CVE ID         : CVE-2026-44235 CVE-2026-44236

    Two issues were discovered in librabbitmq, a C-language client
    library used to communicate with RabbitMQ servers using the Advanced
    Message Queuing Protocol (AMQP).

    CVE-2026-44235

        A size_t underflow in AMQP frame length computation could have
        led to an out-of-bounds read.

    CVE-2026-44236

        A heap buffer overflow in AMQP login handshake via undersized
        connection.tune.frame_max.

    For Debian 11 bullseye, these problems have been fixed in version
    0.10.0-1+deb11u2.

    For Debian 12 bookworm, these problems have been fixed in version
    0.11.0-1+deb12u2.

    We recommend that you upgrade your librabbitmq packages.
