EulerOS 2.0 SP9 : python-cryptography (EulerOS-SA-2023-2340)

medium Nessus Plugin ID 178085

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-cryptography packages.
