The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4754-4 advisory.

    USN-4754-1 fixed vulnerabilities in Python. Because of a regression, a subsequent update removed the fix     for CVE-2021-3177. This update reinstates the security fix for CVE-2021-3177.

    We apologize for the inconvenience.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1761 advisory.

    Python is an interpreted, interactive, object-oriented programming language that supports modules,     classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 packages provide a     stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and     PostgreSQL.

    Security Fix(es):

    * python: CRLF injection via HTTP request method in httplib/http.client (CVE-2020-26116)

    * python-urllib3: CRLF injection via HTTP request method (CVE-2020-26137)

    * python-lxml: mXSS due to the use of improper parser (CVE-2020-27783)

    * python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3252 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,     classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to     many system calls and libraries, as well as to various windowing systems.

    Security Fix(es):

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

    * python-jinja2: ReDoS vulnerability due to the sub-pattern (CVE-2020-28493)

    * python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

    * python-babel: Relative path traversal allows attacker to load arbitrary locale files and execute     arbitrary code (CVE-2021-20095)

    * python-pygments: Infinite loop in SML lexer may lead to DoS (CVE-2021-20270)

    * 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-pygments: ReDoS via crafted malicious input (CVE-2021-27291)

    Additional information

    * Changes in the default separator for the Python urllib parsing functions

    To mitigate the Web Cache Poisoning CVE-2021-23336 in the Python urllib library, the default separator for     the urllib.parse.parse_qsl and urllib.parse.parse_qs functions is being changed from both ampersand (&)     and semicolon (;) to only an ampersand.

    The change of the default separator is potentially backwards incompatible, therefore Red Hat provides a     way to configure the behavior in Python packages where the default separator has been changed. In     addition, the affected urllib parsing functions issue a warning if they detect that a customers     application has been affected by the change.

    For more information, see the Knowledgebase article Mitigation of Web Cache Poisoning in the Python     urllib library (CVE-2021-23336) linked from the References section.
