LIN1021-23470 : Security Advisory - glib-2.0 - CVE-2021-28153

Created: Apr 28, 2026    Updated: Apr 30, 2026
Found In Version: 10.21.20.27
Severity: Standard
Applicable for: Wind River Linux LTS 21
Component/s: Userspace

Description

An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.)
