Gentoo Linux Security Advisory

Title: GDM: Privilege escalation (GLSA 200606-14)
Severity: high
Exploitable: local
Date: June 12, 2006
Updated: June 19, 2006
Bug(s): #135027
ID: 200606-14

Synopsis

An authentication error in GDM could allow users to gain elevated privileges.

Background

GDM is the GNOME display manager.

Affected Packages

Package: gnome-base/gdm
Vulnerable: < 2.8.0.8
Unaffected: >= 2.8.0.8
Architectures: All supported architectures


Description

GDM allows a normal user to access the configuration manager.

Impact

When the "face browser" in GDM is enabled, a normal user can use the "configure login manager" with his/her own password instead of the root password, and thus gain additional privileges.

Workaround

There is no known workaround at this time.

Resolution

All GDM users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-base/gdm-2.8.0.8"


References
