The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4162 advisory.

  - python-psutil: Double free because of refcount mishandling (CVE-2019-18874)

  - python: Unsafe use of eval() on data retrieved via HTTP in the test suite (CVE-2020-27619)

  - python-jinja2: ReDoS vulnerability in the urlize filter (CVE-2020-28493)

  - python: Web cache poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a semicolon in     query parameters (CVE-2021-23336)

  - python-lxml: Missing input sanitization for formaction HTML5 attributes may lead to XSS (CVE-2021-28957)

  - python-ipaddress: Improper input validation of octal strings (CVE-2021-29921)

  - python-urllib3: ReDoS in the parsing of authority part of URL (CVE-2021-33503)

  - python: Information disclosure via pydoc (CVE-2021-3426)

  - python-pip: Incorrect handling of unicode separators in git references (CVE-2021-3572)

  - python-babel: Relative path traversal allows attacker to load arbitrary locale files and     execute arbitrary code (CVE-2021-42771)

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-4162 advisory.

  - The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before     3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and     urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query     parameters using a semicolon (;), they can cause a difference in the interpretation of the request between     the proxy (running with default configuration) and the server. This can result in malicious requests being     cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and     therefore would not include it in a cache key of an unkeyed parameter. (CVE-2021-23336)

  - psutil (aka python-psutil) through 5.6.5 can have a double free. This occurs because of refcount     mishandling within a while or for loop that converts system data into a Python object. (CVE-2019-18874)

  - Babel.Locale in Babel before 2.9.1 allows attackers to load arbitrary locale .dat files (containing     serialized Python objects) via directory traversal, leading to code execution. (CVE-2021-42771)

  - A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote     attacker could possibly use this issue to install a different revision on a repository. The highest threat     from this vulnerability is to data integrity. This is fixed in python-pip version 21.1. (CVE-2021-3572)

  - This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the     `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most     exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format     user content instead of the urlize filter, or by implementing request timeouts and limiting process     memory. (CVE-2020-28493)

  - An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling     the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute     allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS     code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.
    (CVE-2021-28957)

  - In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP     address string. This (in some situations) allows attackers to bypass access control that is based on IP     addresses. (CVE-2021-29921)

  - There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince     another local or adjacent user to start a pydoc server could access the server and use it to disclose     sensitive information belonging to the other user that they would not normally be able to access. The     highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9,     Python versions before 3.9.3 and Python versions before 3.10.0a7. (CVE-2021-3426)

  - An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in     the authority component, the authority regular expression exhibits catastrophic backtracking, causing a     denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect.
