Description

This security bulletin contains information about 1 vulnerability.


1) Untrusted search path (CVE-ID: CVE-2025-59042)

CWE-ID: CWE-426 - Untrusted Search Path

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a special entry being appended to sys.path during the bootstrap process of a PyInstaller-frozen application, and due to the bootstrap script attempting to load an optional module for bytecode decryption while this entry is still present in sys.path. A local user can trick the installer under certain circumstances into executing a malicious code and escalate privileges on the system.


Remediation

Install update from vendor's website.
