EulerOS Virtualization 2.15.1 : python-virtualenv (EulerOS-SA-2026-4575)

medium Nessus Plugin ID 377381

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 virtualenv is a tool for creating isolated virtual python environments. Prior to version 20.36.1, TOCTOU (Time-of-Check-Time-of-Use) vulnerabilities in virtualenv allow local attackers to perform symlink-based attacks on directory creation operations. An attacker with local access can exploit a race condition between directory existence checks and creation to redirect virtualenv's app_data and lock file operations to attacker-controlled locations. This issue has been patched in version 20.36.1.(CVE-2026-22702)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization python-virtualenv 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 python-virtualenv packages.
