"The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-7454-1 advisory.

    It was discovered that the libarchive bsdunzip utility incorrectly handled certain ZIP archive files. If a
    user or automated system were tricked into processing a specially crafted ZIP archive, an attacker could
    use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute
    arbitrary code. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-1632)

    It was discovered that libarchive incorrectly handled certain TAR archive files. If a user or automated
    system were tricked into processing a specially crafted TAR archive, an attacker could use this issue to
    cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2025-25724)
