The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7744-1 advisory.

    It was discovered that QEMU incorrectly handled certain virtio devices. A privileged guest attacker could     use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code.
    This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3446)

    It was discovered that QEMU incorrectly handled SDHCI device emulation. A guest attacker could possibly     use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu     22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3447)

    It was discovered that QEMU incorrectly handled calculating the checksum of a short-sized fragmented     packet. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of     service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-3567)

    It was discovered that the QEMU qemu-img utility incorrectly handled certain crafted image files. An     attacker could use this issue to cause QEMU to consume resources, leading to a denial of service, or     possibly read and write to an existing external file. This issue only affected Ubuntu 22.04 LTS and Ubuntu     24.04 LTS. (CVE-2024-4467)

    It was discovered that QEMU incorrectly handled the RSS feature on virtio-net devices. A privileged guest     attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue     only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-6505)

    It was discovered that QEMU incorrectly handled the NBD server. An attacker could use this issue to cause     QEMU to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and     Ubuntu 24.04 LTS. (CVE-2024-7409)

    It was discovered that QEMU incorrectly handled certain USB devices. A guest attacker could possibly use     this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04     LTS and Ubuntu 24.04 LTS. (CVE-2024-8354)

    It was discovered that the QEMU package incorrectly set up a binfmt_misc registration with the C     (Credential) flag. A local attacker could use this with a suid/sgid binary to escalate privileges. This     update will no longer run foreign-architecture binaries with suid/sgid with elevated privileges.
