"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2021:0056 advisory.

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

    CVE-2021-22918:
    Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is
    used to convert strings to ASCII. The pointer p is read and increased without checking whether it is
    beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information
    disclosures or crashes. This function can be triggered via uv_getaddrinfo().

    CVE-2021-23362:
    The package hosted-git-info before 3.0.8 are vulnerable to Regular Expression Denial of Service (ReDoS)
    via regular expression shortcutMatch in the fromUrl function in index.js. The affected regular expression
    exhibits polynomial worst-case time complexity.

    CVE-2021-27290:
    ssri 5.2.2-8.0.0, fixed in 8.0.1, processes SRIs using a regular expression which is vulnerable to a
    denial of service. Malicious SRIs could take an extremely long time to process, leading to denial of
    service. This issue only affects consumers using the strict option.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
