Alpine: multiple py3-cryptography packages: security update to 46.0.7-r0

medium Tenable Cloud Security Plugin ID 440103

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
 Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates,
 and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer
 named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the
 leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This
 issue has been patched in version 46.0.6. (CVE-2026-34073)

 - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
 From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers
 (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.
 (CVE-2026-39892)

Solution

Update the py3-cryptography library and its related packages to version 46.0.7-r0 or later.
