"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-1000019:
    libarchive version commit bf9aec176c6748f0ee7a678c5f9f9555b9a757c1 onwards (release v3.0.2 onwards)
    contains a CWE-125: Out-of-bounds Read vulnerability in 7zip decompression,
    archive_read_support_format_7zip.c, header_bytes() that can result in a crash (denial of service). This
    attack appears to be exploitable via the victim opening a specially crafted 7zip file.

    CVE-2019-1000020:
    libarchive version commit 5a98dcf8a86364b3c2c469c85b93647dfb139961 onwards (version v2.8.0 onwards)
    contains a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in ISO9660
    parser, archive_read_support_format_iso9660.c, read_CE()/parse_rockridge() that can result in DoS by
    infinite loop. This attack appears to be exploitable via the victim opening a specially crafted ISO9660
    file.

    CVE-2019-18408:
    archive_read_format_rar_read_data in archive_read_support_format_rar.c in libarchive before 3.4.0 has a
    use-after-free in a certain ARCHIVE_FAILED situation, related to Ppmd7_DecodeSymbol.

    CVE-2019-19221:
    In Libarchive 3.4.0, archive_wstring_append_from_mbs in archive_string.c has an out-of-bounds read because
    of an incorrect mbrtowc or mbtowc call. For example, bsdtar crashes via a crafted archive.

    CVE-2021-23177:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when
    announcing a new security problem. When the candidate has been publicized, the details for this candidate
    will be provided.

    CVE-2021-31566:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when
    announcing a new security problem. When the candidate has been publicized, the details for this candidate
    will be provided.
