It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-459 advisory.

    cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In     affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol,     but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated,     thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an     exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8.
    (CVE-2023-23931)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

According to the versions of the python-cryptography package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

The version of AOS installed on the remote host is prior to 7.0. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.0 advisory.

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

  - An issue was discovered in libexpat before 2.6.3. nextScaffoldPart in xmlparse.c can have an integer     overflow for m_groupSize on 32-bit platforms (where UINT_MAX equals SIZE_MAX). (CVE-2024-45492)

  - Improper Handling of Exceptional Conditions, Uncontrolled Resource Consumption vulnerability in Apache     Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers     correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect     infinite timeout which allowed connections to remain open which should have been closed. This issue     affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from 9.0.0-M1     through 9.0.89. The following versions were EOL at the time the CVE was created but are known to be     affected: 8.5.0 though 8.5.100. Users are recommended to upgrade to version 11.0.0-M21, 10.1.25 or 9.0.90,     which fixes the issue. (CVE-2024-34750)

  - A vulnerability was found in libndp. This flaw allows a local malicious user to cause a buffer overflow in     NetworkManager, triggered by sending a malformed IPv6 router advertisement packet. This issue occurred as     libndp was not correctly validating the route length information. (CVE-2024-5564)

  - Python Packaging Authority (PyPA) setuptools before 65.5.1 allows remote attackers to cause a denial of     service via HTML in a crafted package or custom PackageIndex page. There is a Regular Expression Denial of     Service (ReDoS) in package_index.py. (CVE-2022-40897)

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

The version of AOS installed on the remote host is prior to 6.8.1.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.8.1.5 advisory.

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

  - urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header     special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.
    However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP     redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been     patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)
