    Debian Bug     : 1034179 1041102 1068821

    Multiple security issues were discovered in QEMU, a fast processor
    emulator, which could result in denial of service or information leak.

    CVE-2023-1544

        Potential out-of-bounds read and crash via VMWare's paravirtual RDMA device.

    CVE-2023-3019

        Use-after-free error in the e1000e NIC emulation.

    CVE-2023-5088

        IDE guest I/O operation addressed to an arbitrary disk offset may
        potentially allow to overwrite the VM's boot code.

    CVE-2023-6693

        Stack based buffer overflow in the virtio-net device emulation that may be
        exploited to cause information leak.

    CVE-2024-3447

        Heap-based buffer overflow in SDHCI device emulation.

    For Debian 11 bullseye, these problems have been fixed in version
    1:5.2+dfsg-11+deb11u4.

    We recommend that you upgrade your qemu packages.

    its security tracker page at:
