Red Hat: CVE-2021-28153: CVE-2021-28153 glib: g_file_replace() with G_FILE_CREATE_REPLACE_DESTINATION creates empty target for dangling symlink (Multiple Advisories)
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.)
