EulerOS 2.0 SP11 : pyOpenSSL (EulerOS-SA-2026-2224)

medium Nessus Plugin ID 319947

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the pyOpenSSL packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 0.14.0 and prior to version 26.0.0, if a user provided callback to `set_tlsext_servername_callback` raised an unhandled exception, this would result in a connection being accepted. If a user was relying on this callback for any security- sensitive behavior, this could allow bypassing it. Starting in version 26.0.0, unhandled exceptions now result in rejecting the connection.(CVE-2026-27448)

Tenable has extracted the preceding description block directly from the EulerOS pyOpenSSL security advisory.

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

Solution

Update the affected pyOpenSSL packages.
