Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Improper locking

EUVDB-ID: #VU108044

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-2817

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

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

The vulnerability exists due to improper locking mechanism in Firefox Updater. A medium-integrity user process can  interfere with the SYSTEM-level updater by manipulating the file-locking behavior by injecting code into the user-privileged process. A local user or malicious software installed on the system can bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation.

Mitigation

Update the affected package MozillaThunderbird to the latest version.
