Echo: cryptography: security update to 49.0.0python-cryptography: security update to 1:43.0.0-3+deb13u1+e3

high Tenable Self-Hosted Container Security Plugin ID 459588

Description

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

 - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In
 versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com,
 and the leaf certificate has a wildcard in its DNS SAN of *.example.com, python-cryptography's verifier
 accepts which allows escaping outside of the permitted names. The core issue is in DNSConstraint::matches,
 where a wildcard pattern was treated as matching a more-specific permitted constraint even though
 *.example.com can expand to sibling names such as bar.example.com outside foo.example.com. This allows
 acceptance of an invalid certificate chain. This issue is fixed in 49.0.0. (CVE-2026-69248)

Solution

Update the python-cryptography library and its related packages to version 1:43.0.0-3+deb13u1+e3 or later.
