"The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2021-5171 advisory.

  - This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application
    that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited
    further depending on the context. (CVE-2020-7788)

  - This affects the package glob-parent before 5.1.2. The enclosure regex used to check for strings ending in
    enclosure containing path separator. (CVE-2020-28469)

  - ansi-regex is vulnerable to Inefficient Regular Expression Complexity (CVE-2021-3807)

  - json-schema is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype
    Pollution') (CVE-2021-3918)

  - The normalize-url package before 4.5.1, 5.x before 5.3.1, and 6.x before 6.0.1 for Node.js has a ReDoS
    (regular expression denial of service) issue because it has exponential performance for data: URLs.
    (CVE-2021-33502)

  - The parser in accepts requests with a space (SP) right after the header name before the colon. This can
    lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6. (CVE-2021-22959)

  - The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of
    chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions. (CVE-2021-22960)

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