The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the python3.9-3.9.16-1.el9 build changelog.

  - Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-     default configuration. The Python multiprocessing library, when used with the forkserver start method on     Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which     in many system configurations means any user on the same machine. Pickles can execute arbitrary code.
    Thus, this allows for local user privilege escalation to the user that any forkserver process is running     as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start     method for multiprocessing is not the default start method. This issue is Linux specific because only     Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract     namespace sockets by default. Support for users manually specifying an abstract namespace socket was added     as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do     that in CPython before 3.9. (CVE-2022-42919)

  - An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name     being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by     remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:6793 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.

    The following packages have been upgraded to a later upstream version: rh-python38-python (3.8.18), rh-     python38-python-cryptography (2.8), rh-python38-python-pip (19.3.1), rh-python38-python-requests (2.22.0),     rh-python38-python-setuptools (41.6.0), rh-python38-python-wheel (0.33.6).

    Security Fix(es):

    * python: urllib.parse url blocklisting bypass (CVE-2023-24329)

    * python: TLS handshake bypass (CVE-2023-40217)

    * python: tarfile module directory traversal (CVE-2007-4559)

    * pypa-setuptools: Regular Expression Denial of Service (ReDoS) in package_index.py (CVE-2022-40897)

    * python-wheel: remote attackers can cause denial of service via attacker controlled input to wheel cli     (CVE-2022-40898)

    * python: CPU denial of service via inefficient IDNA decoder (CVE-2022-45061)

    * python-cryptography: memory corruption via immutable objects (CVE-2023-23931)

    * python-requests: Unintended leak of Proxy-Authorization header (CVE-2023-32681)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:2764 advisory.

  - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when     using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for     1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not     affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

  - ** DISPUTED ** Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to     no protection against multiple (/) at the beginning of URI path which may leads to information disclosure.
    NOTE: this is disputed by a third party because the http.server.html documentation page states Warning:
    http.server is not recommended for production. It only implements basic security checks. (CVE-2021-28861)

  - An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name     being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by     remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. (CVE-2022-45061)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-104 advisory.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0748-1 advisory.

  - In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands     discovered in the system mailcap file. This may allow attackers to inject shell commands into applications     that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or     arguments). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)

  - The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer     overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties.
    This occurs in the sponge function interface. (CVE-2022-37454)
