There is no fixed version for Centos:8 glib2-static.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2-static package and not the glib2-static package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.
