"The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2021:2319-1 advisory.

  - The package y18n before 3.2.2, 4.0.1 and 5.0.5, is vulnerable to Prototype Pollution. (CVE-2020-7774)

  - 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-2021-22918)

  - 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-2021-23362)

  - 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. (CVE-2021-27290)

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