Summary

Details

An issue was discovered in GNOME GLib before 2.66.8. When gfilereplace() is used with GFILECREATEREPLACEDESTINATION 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.)
