SCA: security update for cryptography (GHSA-jwv3-5hgf-82ww)

high Tenable Self-Hosted Container Security Plugin ID 445600

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - python-cryptography is a package designed to expose cryptographic primitives and recipes to Python
 developers. Prior to 49.0.0, when resolving invalid certificate chains that include duplicate copies of
 self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential
 blowup. Although the limitation that the chain depth cannot exceed a specified maximum depth prevents
 unbounded recursion and guarantees termination, an attacker-controlled certificate chain can lead the
 processing to easily take more than 5s to reject in testing. This amplification could form the basis for a
 resource exhaustion denial of service attack. The core issue arises in the recursive nature of
 build_chain_inner, which does not de-duplicate against previously analyzed candidates. As the correctness
 of validation is not affected, the integrity of a system cannot be compromised through this vector, only
 its availability. This issue is fixed in 49.0.0. (CVE-2026-69249)

Solution

Update the cryptography library and its related packages to version 49.0.0 or later.
