Overview

GLib vulnerability

Releases

Packages

Details

Arand Nash discovered that applications linked to GLib (e.g. Nautilus)
did not correctly copy symlinks. If a user copied symlinks with GLib,
the symlink target files would become world-writable, allowing local
attackers to gain access to potentially sensitive information.
