QID 670829

Python is an accessible, high-level, dynamically typed, interpreted programming language, designed with an emphasis on code readability. It includes an extensive standard library, and has a vast ecosystem of third-party libraries. The python3 package provides the "python3" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3-libs package, which should be installed automatically along with python3. The remaining parts of the Python standard library are broken out into the python3-tkinter and python3-test packages, which may need to be installed separately. Documentation for Python is provided in the python3-docs package. Packages containing additional libraries for Python are generally named with the "python3-" prefix. Security Fix(es): 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)
Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

An arbitrary attacker may exploit this vulnerability to compromise the system.
