OESA-2021-1044 (CVE-2019-3825)

Vulnerability from osv_openeuler – Published: 2021-03-05 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

gdm security update

Details

The GNOME Display Manager is a system service that is responsible for providing graphical log-ins and managing local and remote displays, and if the session doesn't provide a display server, GDM will start the display server. It also provides initiate functionality for user-switching, so multiple users can be logged in at the same time.

Security Fix(es):

A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.(CVE-2019-3825)

Severity

6.4 (Medium)
